Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70666, here are decompositions:

3 + 70663 = 70666
47 + 70619 = 70666
59 + 70607 = 70666
83 + 70583 = 70666
137 + 70529 = 70666
179 + 70487 = 70666
227 + 70439 = 70666
293 + 70373 = 70666

Showing the first eight; more decompositions exist.
