Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637908, here are decompositions:

61 + 8637847 = 8637908
79 + 8637829 = 8637908
211 + 8637697 = 8637908
241 + 8637667 = 8637908
271 + 8637637 = 8637908
457 + 8637451 = 8637908
571 + 8637337 = 8637908
607 + 8637301 = 8637908

Showing the first eight; more decompositions exist.
