Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680864, here are decompositions:

41 + 8680823 = 8680864
53 + 8680811 = 8680864
83 + 8680781 = 8680864
131 + 8680733 = 8680864
167 + 8680697 = 8680864
173 + 8680691 = 8680864
233 + 8680631 = 8680864
251 + 8680613 = 8680864

Showing the first eight; more decompositions exist.
