Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637258, here are decompositions:

5 + 8637253 = 8637258
11 + 8637247 = 8637258
31 + 8637227 = 8637258
79 + 8637179 = 8637258
107 + 8637151 = 8637258
127 + 8637131 = 8637258
139 + 8637119 = 8637258
151 + 8637107 = 8637258

Showing the first eight; more decompositions exist.
