Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628724, here are decompositions:

47 + 8628677 = 8628724
101 + 8628623 = 8628724
173 + 8628551 = 8628724
281 + 8628443 = 8628724
317 + 8628407 = 8628724
347 + 8628377 = 8628724
431 + 8628293 = 8628724
491 + 8628233 = 8628724

Showing the first eight; more decompositions exist.
