Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637746, here are decompositions:

79 + 8637667 = 8637746
109 + 8637637 = 8637746
127 + 8637619 = 8637746
223 + 8637523 = 8637746
367 + 8637379 = 8637746
373 + 8637373 = 8637746
409 + 8637337 = 8637746
457 + 8637289 = 8637746

Showing the first eight; more decompositions exist.
