Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629722, here are decompositions:

11 + 8629711 = 8629722
41 + 8629681 = 8629722
43 + 8629679 = 8629722
61 + 8629661 = 8629722
71 + 8629651 = 8629722
109 + 8629613 = 8629722
139 + 8629583 = 8629722
239 + 8629483 = 8629722

Showing the first eight; more decompositions exist.
