Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706680, here are decompositions:

13 + 8706667 = 8706680
67 + 8706613 = 8706680
127 + 8706553 = 8706680
223 + 8706457 = 8706680
277 + 8706403 = 8706680
313 + 8706367 = 8706680
331 + 8706349 = 8706680
397 + 8706283 = 8706680

Showing the first eight; more decompositions exist.
