Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637278, here are decompositions:

31 + 8637247 = 8637278
127 + 8637151 = 8637278
211 + 8637067 = 8637278
271 + 8637007 = 8637278
367 + 8636911 = 8637278
379 + 8636899 = 8637278
409 + 8636869 = 8637278
421 + 8636857 = 8637278

Showing the first eight; more decompositions exist.
