Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78080, here are decompositions:

31 + 78049 = 78080
73 + 78007 = 78080
97 + 77983 = 78080
103 + 77977 = 78080
151 + 77929 = 78080
181 + 77899 = 78080
241 + 77839 = 78080
283 + 77797 = 78080

Showing the first eight; more decompositions exist.
