Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637018, here are decompositions:

11 + 8637007 = 8637018
29 + 8636989 = 8637018
31 + 8636987 = 8637018
59 + 8636959 = 8637018
97 + 8636921 = 8637018
101 + 8636917 = 8637018
107 + 8636911 = 8637018
109 + 8636909 = 8637018

Showing the first eight; more decompositions exist.
