Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747512, here are decompositions:

23 + 8747489 = 8747512
29 + 8747483 = 8747512
41 + 8747471 = 8747512
71 + 8747441 = 8747512
89 + 8747423 = 8747512
131 + 8747381 = 8747512
239 + 8747273 = 8747512
251 + 8747261 = 8747512

Showing the first eight; more decompositions exist.
