Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629678, here are decompositions:

17 + 8629661 = 8629678
41 + 8629637 = 8629678
269 + 8629409 = 8629678
479 + 8629199 = 8629678
509 + 8629169 = 8629678
521 + 8629157 = 8629678
569 + 8629109 = 8629678
599 + 8629079 = 8629678

Showing the first eight; more decompositions exist.
