Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629630, here are decompositions:

17 + 8629613 = 8629630
47 + 8629583 = 8629630
197 + 8629433 = 8629630
281 + 8629349 = 8629630
389 + 8629241 = 8629630
431 + 8629199 = 8629630
461 + 8629169 = 8629630
491 + 8629139 = 8629630

Showing the first eight; more decompositions exist.
