Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641736, here are decompositions:

3 + 8641733 = 8641736
67 + 8641669 = 8641736
193 + 8641543 = 8641736
223 + 8641513 = 8641736
283 + 8641453 = 8641736
307 + 8641429 = 8641736
409 + 8641327 = 8641736
463 + 8641273 = 8641736

Showing the first eight; more decompositions exist.
