Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645746, here are decompositions:

17 + 8645729 = 8645746
59 + 8645687 = 8645746
89 + 8645657 = 8645746
113 + 8645633 = 8645746
149 + 8645597 = 8645746
167 + 8645579 = 8645746
269 + 8645477 = 8645746
419 + 8645327 = 8645746

Showing the first eight; more decompositions exist.
