Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718466, here are decompositions:

5 + 8718461 = 8718466
47 + 8718419 = 8718466
59 + 8718407 = 8718466
89 + 8718377 = 8718466
269 + 8718197 = 8718466
353 + 8718113 = 8718466
467 + 8717999 = 8718466
479 + 8717987 = 8718466

Showing the first eight; more decompositions exist.
