Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470784, here are decompositions:

5 + 470779 = 470784
53 + 470731 = 470784
73 + 470711 = 470784
131 + 470653 = 470784
137 + 470647 = 470784
157 + 470627 = 470784
163 + 470621 = 470784
191 + 470593 = 470784

Showing the first eight; more decompositions exist.
