Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640124, here are decompositions:

107 + 8640017 = 8640124
137 + 8639987 = 8640124
173 + 8639951 = 8640124
461 + 8639663 = 8640124
557 + 8639567 = 8640124
593 + 8639531 = 8640124
617 + 8639507 = 8640124
683 + 8639441 = 8640124

Showing the first eight; more decompositions exist.
