Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71980, here are decompositions:

17 + 71963 = 71980
47 + 71933 = 71980
71 + 71909 = 71980
101 + 71879 = 71980
113 + 71867 = 71980
131 + 71849 = 71980
137 + 71843 = 71980
173 + 71807 = 71980

Showing the first eight; more decompositions exist.
