Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612638, here are decompositions:

5 + 8612633 = 8612638
11 + 8612627 = 8612638
107 + 8612531 = 8612638
227 + 8612411 = 8612638
239 + 8612399 = 8612638
599 + 8612039 = 8612638
647 + 8611991 = 8612638
677 + 8611961 = 8612638

Showing the first eight; more decompositions exist.
