Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637636, here are decompositions:

17 + 8637619 = 8637636
19 + 8637617 = 8637636
109 + 8637527 = 8637636
113 + 8637523 = 8637636
127 + 8637509 = 8637636
257 + 8637379 = 8637636
263 + 8637373 = 8637636
313 + 8637323 = 8637636

Showing the first eight; more decompositions exist.
