Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637944, here are decompositions:

97 + 8637847 = 8637944
157 + 8637787 = 8637944
277 + 8637667 = 8637944
307 + 8637637 = 8637944
421 + 8637523 = 8637944
463 + 8637481 = 8637944
571 + 8637373 = 8637944
607 + 8637337 = 8637944

Showing the first eight; more decompositions exist.
