Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87646, here are decompositions:

3 + 87643 = 87646
5 + 87641 = 87646
17 + 87629 = 87646
23 + 87623 = 87646
59 + 87587 = 87646
89 + 87557 = 87646
107 + 87539 = 87646
137 + 87509 = 87646

Showing the first eight; more decompositions exist.
