Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620674, here are decompositions:

11 + 8620663 = 8620674
37 + 8620637 = 8620674
43 + 8620631 = 8620674
53 + 8620621 = 8620674
71 + 8620603 = 8620674
103 + 8620571 = 8620674
107 + 8620567 = 8620674
131 + 8620543 = 8620674

Showing the first eight; more decompositions exist.
