Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637608, here are decompositions:

127 + 8637481 = 8637608
157 + 8637451 = 8637608
181 + 8637427 = 8637608
229 + 8637379 = 8637608
271 + 8637337 = 8637608
307 + 8637301 = 8637608
457 + 8637151 = 8637608
541 + 8637067 = 8637608

Showing the first eight; more decompositions exist.
