Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637812, here are decompositions:

193 + 8637619 = 8637812
331 + 8637481 = 8637812
433 + 8637379 = 8637812
439 + 8637373 = 8637812
523 + 8637289 = 8637812
661 + 8637151 = 8637812
709 + 8637103 = 8637812
751 + 8637061 = 8637812

Showing the first eight; more decompositions exist.
