Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627864, here are decompositions:

13 + 8627851 = 8627864
31 + 8627833 = 8627864
151 + 8627713 = 8627864
163 + 8627701 = 8627864
283 + 8627581 = 8627864
331 + 8627533 = 8627864
337 + 8627527 = 8627864
367 + 8627497 = 8627864

Showing the first eight; more decompositions exist.
