Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628874, here are decompositions:

17 + 8628857 = 8628874
83 + 8628791 = 8628874
101 + 8628773 = 8628874
197 + 8628677 = 8628874
227 + 8628647 = 8628874
251 + 8628623 = 8628874
431 + 8628443 = 8628874
467 + 8628407 = 8628874

Showing the first eight; more decompositions exist.
