Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86646, here are decompositions:

17 + 86629 = 86646
19 + 86627 = 86646
47 + 86599 = 86646
59 + 86587 = 86646
67 + 86579 = 86646
73 + 86573 = 86646
107 + 86539 = 86646
113 + 86533 = 86646

Showing the first eight; more decompositions exist.
