Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641502, here are decompositions:

31 + 8641471 = 8641502
73 + 8641429 = 8641502
151 + 8641351 = 8641502
193 + 8641309 = 8641502
229 + 8641273 = 8641502
271 + 8641231 = 8641502
409 + 8641093 = 8641502
439 + 8641063 = 8641502

Showing the first eight; more decompositions exist.
