Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620956, here are decompositions:

5 + 8620951 = 8620956
7 + 8620949 = 8620956
13 + 8620943 = 8620956
59 + 8620897 = 8620956
83 + 8620873 = 8620956
109 + 8620847 = 8620956
199 + 8620757 = 8620956
229 + 8620727 = 8620956

Showing the first eight; more decompositions exist.
