Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637628, here are decompositions:

11 + 8637617 = 8637628
17 + 8637611 = 8637628
101 + 8637527 = 8637628
107 + 8637521 = 8637628
137 + 8637491 = 8637628
179 + 8637449 = 8637628
317 + 8637311 = 8637628
401 + 8637227 = 8637628

Showing the first eight; more decompositions exist.
