Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637284, here are decompositions:

31 + 8637253 = 8637284
37 + 8637247 = 8637284
151 + 8637133 = 8637284
181 + 8637103 = 8637284
193 + 8637091 = 8637284
223 + 8637061 = 8637284
277 + 8637007 = 8637284
367 + 8636917 = 8637284

Showing the first eight; more decompositions exist.
