Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641768, here are decompositions:

59 + 8641709 = 8641768
71 + 8641697 = 8641768
137 + 8641631 = 8641768
197 + 8641571 = 8641768
227 + 8641541 = 8641768
251 + 8641517 = 8641768
347 + 8641421 = 8641768
419 + 8641349 = 8641768

Showing the first eight; more decompositions exist.
