Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620782, here are decompositions:

43 + 8620739 = 8620782
59 + 8620723 = 8620782
61 + 8620721 = 8620782
109 + 8620673 = 8620782
151 + 8620631 = 8620782
179 + 8620603 = 8620782
193 + 8620589 = 8620782
211 + 8620571 = 8620782

Showing the first eight; more decompositions exist.
