Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641340, here are decompositions:

13 + 8641327 = 8641340
31 + 8641309 = 8641340
67 + 8641273 = 8641340
109 + 8641231 = 8641340
193 + 8641147 = 8641340
277 + 8641063 = 8641340
373 + 8640967 = 8641340
457 + 8640883 = 8641340

Showing the first eight; more decompositions exist.
