Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620836, here are decompositions:

79 + 8620757 = 8620836
89 + 8620747 = 8620836
97 + 8620739 = 8620836
109 + 8620727 = 8620836
113 + 8620723 = 8620836
149 + 8620687 = 8620836
163 + 8620673 = 8620836
173 + 8620663 = 8620836

Showing the first eight; more decompositions exist.
