Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637906, here are decompositions:

37 + 8637869 = 8637906
59 + 8637847 = 8637906
127 + 8637779 = 8637906
157 + 8637749 = 8637906
239 + 8637667 = 8637906
269 + 8637637 = 8637906
379 + 8637527 = 8637906
383 + 8637523 = 8637906

Showing the first eight; more decompositions exist.
