Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470870, here are decompositions:

3 + 470867 = 470870
7 + 470863 = 470870
79 + 470791 = 470870
139 + 470731 = 470870
151 + 470719 = 470870
181 + 470689 = 470870
223 + 470647 = 470870
271 + 470599 = 470870

Showing the first eight; more decompositions exist.
