Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637274, here are decompositions:

11 + 8637263 = 8637274
17 + 8637257 = 8637274
47 + 8637227 = 8637274
71 + 8637203 = 8637274
167 + 8637107 = 8637274
257 + 8637017 = 8637274
353 + 8636921 = 8637274
641 + 8636633 = 8637274

Showing the first eight; more decompositions exist.
