Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637124, here are decompositions:

5 + 8637119 = 8637124
17 + 8637107 = 8637124
71 + 8637053 = 8637124
107 + 8637017 = 8637124
137 + 8636987 = 8637124
383 + 8636741 = 8637124
491 + 8636633 = 8637124
521 + 8636603 = 8637124

Showing the first eight; more decompositions exist.
