Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470644, here are decompositions:

17 + 470627 = 470644
23 + 470621 = 470644
47 + 470597 = 470644
113 + 470531 = 470644
131 + 470513 = 470644
173 + 470471 = 470644
191 + 470453 = 470644
197 + 470447 = 470644

Showing the first eight; more decompositions exist.
