Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641514, here are decompositions:

43 + 8641471 = 8641514
61 + 8641453 = 8641514
163 + 8641351 = 8641514
241 + 8641273 = 8641514
283 + 8641231 = 8641514
367 + 8641147 = 8641514
421 + 8641093 = 8641514
547 + 8640967 = 8641514

Showing the first eight; more decompositions exist.
