Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641382, here are decompositions:

31 + 8641351 = 8641382
73 + 8641309 = 8641382
109 + 8641273 = 8641382
151 + 8641231 = 8641382
433 + 8640949 = 8641382
499 + 8640883 = 8641382
523 + 8640859 = 8641382
601 + 8640781 = 8641382

Showing the first eight; more decompositions exist.
