Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628694, here are decompositions:

17 + 8628677 = 8628694
47 + 8628647 = 8628694
71 + 8628623 = 8628694
251 + 8628443 = 8628694
311 + 8628383 = 8628694
317 + 8628377 = 8628694
401 + 8628293 = 8628694
461 + 8628233 = 8628694

Showing the first eight; more decompositions exist.
