Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637126, here are decompositions:

7 + 8637119 = 8637126
19 + 8637107 = 8637126
23 + 8637103 = 8637126
59 + 8637067 = 8637126
67 + 8637059 = 8637126
73 + 8637053 = 8637126
109 + 8637017 = 8637126
137 + 8636989 = 8637126

Showing the first eight; more decompositions exist.
