Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637776, here are decompositions:

79 + 8637697 = 8637776
109 + 8637667 = 8637776
139 + 8637637 = 8637776
157 + 8637619 = 8637776
283 + 8637493 = 8637776
349 + 8637427 = 8637776
397 + 8637379 = 8637776
439 + 8637337 = 8637776

Showing the first eight; more decompositions exist.
