Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620678, here are decompositions:

5 + 8620673 = 8620678
41 + 8620637 = 8620678
47 + 8620631 = 8620678
89 + 8620589 = 8620678
107 + 8620571 = 8620678
149 + 8620529 = 8620678
179 + 8620499 = 8620678
317 + 8620361 = 8620678

Showing the first eight; more decompositions exist.
