Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668820, here are decompositions:

3 + 8668817 = 8668820
7 + 8668813 = 8668820
19 + 8668801 = 8668820
37 + 8668783 = 8668820
79 + 8668741 = 8668820
109 + 8668711 = 8668820
211 + 8668609 = 8668820
271 + 8668549 = 8668820

Showing the first eight; more decompositions exist.
