Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637756, here are decompositions:

7 + 8637749 = 8637756
59 + 8637697 = 8637756
89 + 8637667 = 8637756
137 + 8637619 = 8637756
139 + 8637617 = 8637756
229 + 8637527 = 8637756
233 + 8637523 = 8637756
263 + 8637493 = 8637756

Showing the first eight; more decompositions exist.
