Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637736, here are decompositions:

227 + 8637509 = 8637736
269 + 8637467 = 8637736
479 + 8637257 = 8637736
509 + 8637227 = 8637736
557 + 8637179 = 8637736
617 + 8637119 = 8637736
677 + 8637059 = 8637736
683 + 8637053 = 8637736

Showing the first eight; more decompositions exist.
