Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637782, here are decompositions:

3 + 8637779 = 8637782
163 + 8637619 = 8637782
331 + 8637451 = 8637782
409 + 8637373 = 8637782
463 + 8637319 = 8637782
619 + 8637163 = 8637782
631 + 8637151 = 8637782
691 + 8637091 = 8637782

Showing the first eight; more decompositions exist.
