Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674780, here are decompositions:

11 + 8674769 = 8674780
53 + 8674727 = 8674780
113 + 8674667 = 8674780
227 + 8674553 = 8674780
269 + 8674511 = 8674780
281 + 8674499 = 8674780
383 + 8674397 = 8674780
419 + 8674361 = 8674780

Showing the first eight; more decompositions exist.
