Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674420, here are decompositions:

11 + 8674409 = 8674420
23 + 8674397 = 8674420
59 + 8674361 = 8674420
71 + 8674349 = 8674420
89 + 8674331 = 8674420
113 + 8674307 = 8674420
149 + 8674271 = 8674420
233 + 8674187 = 8674420

Showing the first eight; more decompositions exist.
