Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620886, here are decompositions:

13 + 8620873 = 8620886
139 + 8620747 = 8620886
163 + 8620723 = 8620886
199 + 8620687 = 8620886
223 + 8620663 = 8620886
283 + 8620603 = 8620886
457 + 8620429 = 8620886
619 + 8620267 = 8620886

Showing the first eight; more decompositions exist.
