Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668790, here are decompositions:

7 + 8668783 = 8668790
79 + 8668711 = 8668790
103 + 8668687 = 8668790
181 + 8668609 = 8668790
241 + 8668549 = 8668790
271 + 8668519 = 8668790
307 + 8668483 = 8668790
331 + 8668459 = 8668790

Showing the first eight; more decompositions exist.
