Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637012, here are decompositions:

5 + 8637007 = 8637012
23 + 8636989 = 8637012
53 + 8636959 = 8637012
89 + 8636923 = 8637012
101 + 8636911 = 8637012
103 + 8636909 = 8637012
113 + 8636899 = 8637012
173 + 8636839 = 8637012

Showing the first eight; more decompositions exist.
