Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65080, here are decompositions:

17 + 65063 = 65080
47 + 65033 = 65080
53 + 65027 = 65080
83 + 64997 = 65080
179 + 64901 = 65080
227 + 64853 = 65080
263 + 64817 = 65080
269 + 64811 = 65080

Showing the first eight; more decompositions exist.
