Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620818, here are decompositions:

61 + 8620757 = 8620818
71 + 8620747 = 8620818
79 + 8620739 = 8620818
97 + 8620721 = 8620818
127 + 8620691 = 8620818
131 + 8620687 = 8620818
179 + 8620639 = 8620818
181 + 8620637 = 8620818

Showing the first eight; more decompositions exist.
