Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668620, here are decompositions:

7 + 8668613 = 8668620
11 + 8668609 = 8668620
43 + 8668577 = 8668620
67 + 8668553 = 8668620
71 + 8668549 = 8668620
73 + 8668547 = 8668620
97 + 8668523 = 8668620
101 + 8668519 = 8668620

Showing the first eight; more decompositions exist.
