Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641044, here are decompositions:

37 + 8641007 = 8641044
67 + 8640977 = 8641044
157 + 8640887 = 8641044
173 + 8640871 = 8641044
227 + 8640817 = 8641044
257 + 8640787 = 8641044
263 + 8640781 = 8641044
277 + 8640767 = 8641044

Showing the first eight; more decompositions exist.
