Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629782, here are decompositions:

11 + 8629771 = 8629782
19 + 8629763 = 8629782
43 + 8629739 = 8629782
71 + 8629711 = 8629782
101 + 8629681 = 8629782
103 + 8629679 = 8629782
131 + 8629651 = 8629782
199 + 8629583 = 8629782

Showing the first eight; more decompositions exist.
