Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637682, here are decompositions:

41 + 8637641 = 8637682
71 + 8637611 = 8637682
173 + 8637509 = 8637682
191 + 8637491 = 8637682
233 + 8637449 = 8637682
359 + 8637323 = 8637682
419 + 8637263 = 8637682
479 + 8637203 = 8637682

Showing the first eight; more decompositions exist.
