Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71008, here are decompositions:

11 + 70997 = 71008
17 + 70991 = 71008
29 + 70979 = 71008
59 + 70949 = 71008
71 + 70937 = 71008
89 + 70919 = 71008
107 + 70901 = 71008
131 + 70877 = 71008

Showing the first eight; more decompositions exist.
