Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637550, here are decompositions:

23 + 8637527 = 8637550
29 + 8637521 = 8637550
41 + 8637509 = 8637550
59 + 8637491 = 8637550
83 + 8637467 = 8637550
101 + 8637449 = 8637550
227 + 8637323 = 8637550
239 + 8637311 = 8637550

Showing the first eight; more decompositions exist.
