Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470808, here are decompositions:

17 + 470791 = 470808
29 + 470779 = 470808
59 + 470749 = 470808
89 + 470719 = 470808
97 + 470711 = 470808
139 + 470669 = 470808
157 + 470651 = 470808
181 + 470627 = 470808

Showing the first eight; more decompositions exist.
