Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629726, here are decompositions:

47 + 8629679 = 8629726
89 + 8629637 = 8629726
113 + 8629613 = 8629726
293 + 8629433 = 8629726
317 + 8629409 = 8629726
383 + 8629343 = 8629726
557 + 8629169 = 8629726
569 + 8629157 = 8629726

Showing the first eight; more decompositions exist.
