Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637744, here are decompositions:

43 + 8637701 = 8637744
47 + 8637697 = 8637744
103 + 8637641 = 8637744
107 + 8637637 = 8637744
127 + 8637617 = 8637744
223 + 8637521 = 8637744
251 + 8637493 = 8637744
263 + 8637481 = 8637744

Showing the first eight; more decompositions exist.
