Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637288, here are decompositions:

31 + 8637257 = 8637288
41 + 8637247 = 8637288
61 + 8637227 = 8637288
109 + 8637179 = 8637288
137 + 8637151 = 8637288
157 + 8637131 = 8637288
181 + 8637107 = 8637288
197 + 8637091 = 8637288

Showing the first eight; more decompositions exist.
