Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654864, here are decompositions:

61 + 8654803 = 8654864
103 + 8654761 = 8654864
151 + 8654713 = 8654864
223 + 8654641 = 8654864
397 + 8654467 = 8654864
433 + 8654431 = 8654864
577 + 8654287 = 8654864
607 + 8654257 = 8654864

Showing the first eight; more decompositions exist.
