Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719718, here are decompositions:

19 + 8719699 = 8719718
37 + 8719681 = 8719718
127 + 8719591 = 8719718
151 + 8719567 = 8719718
199 + 8719519 = 8719718
277 + 8719441 = 8719718
457 + 8719261 = 8719718
499 + 8719219 = 8719718

Showing the first eight; more decompositions exist.
