Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658740, here are decompositions:

31 + 8658709 = 8658740
43 + 8658697 = 8658740
61 + 8658679 = 8658740
67 + 8658673 = 8658740
127 + 8658613 = 8658740
151 + 8658589 = 8658740
157 + 8658583 = 8658740
163 + 8658577 = 8658740

Showing the first eight; more decompositions exist.
