Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8080, here are decompositions:

11 + 8069 = 8080
41 + 8039 = 8080
71 + 8009 = 8080
131 + 7949 = 8080
173 + 7907 = 8080
179 + 7901 = 8080
197 + 7883 = 8080
227 + 7853 = 8080

Showing the first eight; more decompositions exist.
