Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637574, here are decompositions:

47 + 8637527 = 8637574
53 + 8637521 = 8637574
83 + 8637491 = 8637574
107 + 8637467 = 8637574
233 + 8637341 = 8637574
251 + 8637323 = 8637574
263 + 8637311 = 8637574
311 + 8637263 = 8637574

Showing the first eight; more decompositions exist.
