Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637544, here are decompositions:

17 + 8637527 = 8637544
23 + 8637521 = 8637544
53 + 8637491 = 8637544
233 + 8637311 = 8637544
281 + 8637263 = 8637544
317 + 8637227 = 8637544
491 + 8637053 = 8637544
557 + 8636987 = 8637544

Showing the first eight; more decompositions exist.
