Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637230, here are decompositions:

3 + 8637227 = 8637230
67 + 8637163 = 8637230
79 + 8637151 = 8637230
97 + 8637133 = 8637230
127 + 8637103 = 8637230
139 + 8637091 = 8637230
163 + 8637067 = 8637230
223 + 8637007 = 8637230

Showing the first eight; more decompositions exist.
