Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641604, here are decompositions:

61 + 8641543 = 8641604
151 + 8641453 = 8641604
277 + 8641327 = 8641604
331 + 8641273 = 8641604
373 + 8641231 = 8641604
457 + 8641147 = 8641604
541 + 8641063 = 8641604
733 + 8640871 = 8641604

Showing the first eight; more decompositions exist.
