Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70660, here are decompositions:

3 + 70657 = 70660
41 + 70619 = 70660
53 + 70607 = 70660
71 + 70589 = 70660
89 + 70571 = 70660
131 + 70529 = 70660
173 + 70487 = 70660
179 + 70481 = 70660

Showing the first eight; more decompositions exist.
