Aircraft X was departing HCF airspace from CEBEN to CIVIT; Aircraft Y was going AUNTI; A332 to HELOP with a deviation of 30 miles right of route initially. HCF called back to coordinate 60 miles right of route for Aircraft Y which probed green. Thought it was odd at the time; but the angle of deviation of routes could have played into that factor. Later HCF calls back to say Aircraft Y looks like he's deviating more like 90 miles right of route even though he was only cleared 60; looking like he was a bit close to Aircraft X but that Aircraft Y looked like he was going back to what he was cleared. I probed 90 miles; which showed green; then I probed 126 mile to test the conflict with Aircraft X. That showed red with conflict. Went back to probe 100 miles and that was green so I told HCF that it was probing good. Aircraft Y came out cleared 60 miles right of route but was probing 90 miles right of route to cover his possible deviance. There was no conflict showing till Aircraft X crossed CEBEN. At that time it was flashing red. I thought maybe this was because he was on R463 and not A332; thus I re-cleared the Aircraft Y only 50 miles right of route. I did not probe his originally cleared 60 miles right of route. Once Aircraft Y accepted; the conflict was gone. I could have re-probed 60 right of route to confirm if what he was cleared was still good; but at the time of writing this; I'm not sure if it was. Also not sure why 90 right of route would not set off the conflict with Aircraft X but 126 miles would. Will be more restrictive with deviations leaving HCF and separate more with altitude than route.
KZAK Controller reported that a course deviation by one aircraft resulted in an airborne conflict.
