Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637732, here are decompositions:

31 + 8637701 = 8637732
113 + 8637619 = 8637732
211 + 8637521 = 8637732
223 + 8637509 = 8637732
239 + 8637493 = 8637732
241 + 8637491 = 8637732
251 + 8637481 = 8637732
281 + 8637451 = 8637732

Showing the first eight; more decompositions exist.
