Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637368, here are decompositions:

31 + 8637337 = 8637368
67 + 8637301 = 8637368
79 + 8637289 = 8637368
277 + 8637091 = 8637368
307 + 8637061 = 8637368
379 + 8636989 = 8637368
409 + 8636959 = 8637368
457 + 8636911 = 8637368

Showing the first eight; more decompositions exist.
