Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715686, here are decompositions:

13 + 8715673 = 8715686
19 + 8715667 = 8715686
37 + 8715649 = 8715686
97 + 8715589 = 8715686
127 + 8715559 = 8715686
163 + 8715523 = 8715686
277 + 8715409 = 8715686
283 + 8715403 = 8715686

Showing the first eight; more decompositions exist.
