Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668650, here are decompositions:

7 + 8668643 = 8668650
13 + 8668637 = 8668650
37 + 8668613 = 8668650
41 + 8668609 = 8668650
73 + 8668577 = 8668650
79 + 8668571 = 8668650
97 + 8668553 = 8668650
101 + 8668549 = 8668650

Showing the first eight; more decompositions exist.
