Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637166, here are decompositions:

3 + 8637163 = 8637166
47 + 8637119 = 8637166
59 + 8637107 = 8637166
107 + 8637059 = 8637166
113 + 8637053 = 8637166
149 + 8637017 = 8637166
179 + 8636987 = 8637166
257 + 8636909 = 8637166

Showing the first eight; more decompositions exist.
