Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638082, here are decompositions:

31 + 8638051 = 8638082
43 + 8638039 = 8638082
109 + 8637973 = 8638082
139 + 8637943 = 8638082
463 + 8637619 = 8638082
601 + 8637481 = 8638082
631 + 8637451 = 8638082
709 + 8637373 = 8638082

Showing the first eight; more decompositions exist.
