Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640976, here are decompositions:

89 + 8640887 = 8640976
257 + 8640719 = 8640976
263 + 8640713 = 8640976
269 + 8640707 = 8640976
293 + 8640683 = 8640976
389 + 8640587 = 8640976
557 + 8640419 = 8640976
569 + 8640407 = 8640976

Showing the first eight; more decompositions exist.
