Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637430, here are decompositions:

3 + 8637427 = 8637430
89 + 8637341 = 8637430
107 + 8637323 = 8637430
167 + 8637263 = 8637430
173 + 8637257 = 8637430
227 + 8637203 = 8637430
251 + 8637179 = 8637430
311 + 8637119 = 8637430

Showing the first eight; more decompositions exist.
