Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629728, here are decompositions:

17 + 8629711 = 8629728
47 + 8629681 = 8629728
67 + 8629661 = 8629728
131 + 8629597 = 8629728
167 + 8629561 = 8629728
281 + 8629447 = 8629728
379 + 8629349 = 8629728
431 + 8629297 = 8629728

Showing the first eight; more decompositions exist.
