Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624658, here are decompositions:

37 + 8624621 = 8624658
41 + 8624617 = 8624658
59 + 8624599 = 8624658
151 + 8624507 = 8624658
181 + 8624477 = 8624658
199 + 8624459 = 8624658
331 + 8624327 = 8624658
347 + 8624311 = 8624658

Showing the first eight; more decompositions exist.
