Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658650, here are decompositions:

31 + 8658619 = 8658650
37 + 8658613 = 8658650
61 + 8658589 = 8658650
67 + 8658583 = 8658650
73 + 8658577 = 8658650
79 + 8658571 = 8658650
97 + 8658553 = 8658650
157 + 8658493 = 8658650

Showing the first eight; more decompositions exist.
