Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718586, here are decompositions:

5 + 8718581 = 8718586
47 + 8718539 = 8718586
83 + 8718503 = 8718586
167 + 8718419 = 8718586
179 + 8718407 = 8718586
389 + 8718197 = 8718586
587 + 8717999 = 8718586
593 + 8717993 = 8718586

Showing the first eight; more decompositions exist.
