Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470878, here are decompositions:

11 + 470867 = 470878
41 + 470837 = 470878
47 + 470831 = 470878
59 + 470819 = 470878
167 + 470711 = 470878
227 + 470651 = 470878
251 + 470627 = 470878
257 + 470621 = 470878

Showing the first eight; more decompositions exist.
