Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637170, here are decompositions:

7 + 8637163 = 8637170
19 + 8637151 = 8637170
37 + 8637133 = 8637170
67 + 8637103 = 8637170
79 + 8637091 = 8637170
103 + 8637067 = 8637170
109 + 8637061 = 8637170
163 + 8637007 = 8637170

Showing the first eight; more decompositions exist.
