Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726864, here are decompositions:

61 + 8726803 = 8726864
103 + 8726761 = 8726864
127 + 8726737 = 8726864
151 + 8726713 = 8726864
193 + 8726671 = 8726864
277 + 8726587 = 8726864
331 + 8726533 = 8726864
337 + 8726527 = 8726864

Showing the first eight; more decompositions exist.
