Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619678, here are decompositions:

17 + 8619661 = 8619678
29 + 8619649 = 8619678
127 + 8619551 = 8619678
139 + 8619539 = 8619678
167 + 8619511 = 8619678
239 + 8619439 = 8619678
241 + 8619437 = 8619678
251 + 8619427 = 8619678

Showing the first eight; more decompositions exist.
