Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690828, here are decompositions:

7 + 8690821 = 8690828
31 + 8690797 = 8690828
61 + 8690767 = 8690828
151 + 8690677 = 8690828
229 + 8690599 = 8690828
271 + 8690557 = 8690828
277 + 8690551 = 8690828
457 + 8690371 = 8690828

Showing the first eight; more decompositions exist.
