Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690080, here are decompositions:

11 + 8690069 = 8690080
17 + 8690063 = 8690080
83 + 8689997 = 8690080
101 + 8689979 = 8690080
131 + 8689949 = 8690080
137 + 8689943 = 8690080
227 + 8689853 = 8690080
239 + 8689841 = 8690080

Showing the first eight; more decompositions exist.
