Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658782, here are decompositions:

43 + 8658739 = 8658782
73 + 8658709 = 8658782
103 + 8658679 = 8658782
109 + 8658673 = 8658782
163 + 8658619 = 8658782
193 + 8658589 = 8658782
199 + 8658583 = 8658782
211 + 8658571 = 8658782

Showing the first eight; more decompositions exist.
