Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637460, here are decompositions:

11 + 8637449 = 8637460
137 + 8637323 = 8637460
149 + 8637311 = 8637460
197 + 8637263 = 8637460
233 + 8637227 = 8637460
257 + 8637203 = 8637460
281 + 8637179 = 8637460
353 + 8637107 = 8637460

Showing the first eight; more decompositions exist.
