Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637758, here are decompositions:

61 + 8637697 = 8637758
139 + 8637619 = 8637758
277 + 8637481 = 8637758
307 + 8637451 = 8637758
331 + 8637427 = 8637758
379 + 8637379 = 8637758
421 + 8637337 = 8637758
439 + 8637319 = 8637758

Showing the first eight; more decompositions exist.
