Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629624, here are decompositions:

11 + 8629613 = 8629624
41 + 8629583 = 8629624
191 + 8629433 = 8629624
281 + 8629343 = 8629624
383 + 8629241 = 8629624
431 + 8629193 = 8629624
467 + 8629157 = 8629624
701 + 8628923 = 8629624

Showing the first eight; more decompositions exist.
