Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470828, here are decompositions:

37 + 470791 = 470828
79 + 470749 = 470828
97 + 470731 = 470828
109 + 470719 = 470828
139 + 470689 = 470828
181 + 470647 = 470828
229 + 470599 = 470828
277 + 470551 = 470828

Showing the first eight; more decompositions exist.
