Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620718, here are decompositions:

31 + 8620687 = 8620718
79 + 8620639 = 8620718
97 + 8620621 = 8620718
151 + 8620567 = 8620718
349 + 8620369 = 8620718
487 + 8620231 = 8620718
499 + 8620219 = 8620718
577 + 8620141 = 8620718

Showing the first eight; more decompositions exist.
