Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77080, here are decompositions:

11 + 77069 = 77080
89 + 76991 = 77080
131 + 76949 = 77080
137 + 76943 = 77080
167 + 76913 = 77080
173 + 76907 = 77080
197 + 76883 = 77080
233 + 76847 = 77080

Showing the first eight; more decompositions exist.
