Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68080, here are decompositions:

101 + 67979 = 68080
113 + 67967 = 68080
137 + 67943 = 68080
149 + 67931 = 68080
179 + 67901 = 68080
197 + 67883 = 68080
227 + 67853 = 68080
251 + 67829 = 68080

Showing the first eight; more decompositions exist.
