Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637662, here are decompositions:

43 + 8637619 = 8637662
139 + 8637523 = 8637662
181 + 8637481 = 8637662
211 + 8637451 = 8637662
283 + 8637379 = 8637662
373 + 8637289 = 8637662
409 + 8637253 = 8637662
499 + 8637163 = 8637662

Showing the first eight; more decompositions exist.
