Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641756, here are decompositions:

23 + 8641733 = 8641756
47 + 8641709 = 8641756
59 + 8641697 = 8641756
83 + 8641673 = 8641756
113 + 8641643 = 8641756
239 + 8641517 = 8641756
467 + 8641289 = 8641756
509 + 8641247 = 8641756

Showing the first eight; more decompositions exist.
