Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71080, here are decompositions:

11 + 71069 = 71080
41 + 71039 = 71080
83 + 70997 = 71080
89 + 70991 = 71080
101 + 70979 = 71080
131 + 70949 = 71080
167 + 70913 = 71080
179 + 70901 = 71080

Showing the first eight; more decompositions exist.
