Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651768, here are decompositions:

31 + 8651737 = 8651768
79 + 8651689 = 8651768
331 + 8651437 = 8651768
379 + 8651389 = 8651768
409 + 8651359 = 8651768
439 + 8651329 = 8651768
457 + 8651311 = 8651768
487 + 8651281 = 8651768

Showing the first eight; more decompositions exist.
