Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637390, here are decompositions:

11 + 8637379 = 8637390
17 + 8637373 = 8637390
53 + 8637337 = 8637390
67 + 8637323 = 8637390
71 + 8637319 = 8637390
79 + 8637311 = 8637390
89 + 8637301 = 8637390
101 + 8637289 = 8637390

Showing the first eight; more decompositions exist.
