Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638732, here are decompositions:

5 + 8638727 = 8638732
41 + 8638691 = 8638732
71 + 8638661 = 8638732
149 + 8638583 = 8638732
251 + 8638481 = 8638732
269 + 8638463 = 8638732
281 + 8638451 = 8638732
353 + 8638379 = 8638732

Showing the first eight; more decompositions exist.
