Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637048, here are decompositions:

31 + 8637017 = 8637048
41 + 8637007 = 8637048
59 + 8636989 = 8637048
61 + 8636987 = 8637048
89 + 8636959 = 8637048
127 + 8636921 = 8637048
131 + 8636917 = 8637048
137 + 8636911 = 8637048

Showing the first eight; more decompositions exist.
