Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641766, here are decompositions:

19 + 8641747 = 8641766
97 + 8641669 = 8641766
163 + 8641603 = 8641766
223 + 8641543 = 8641766
313 + 8641453 = 8641766
337 + 8641429 = 8641766
439 + 8641327 = 8641766
457 + 8641309 = 8641766

Showing the first eight; more decompositions exist.
