Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470740, here are decompositions:

29 + 470711 = 470740
71 + 470669 = 470740
89 + 470651 = 470740
113 + 470627 = 470740
131 + 470609 = 470740
227 + 470513 = 470740
239 + 470501 = 470740
251 + 470489 = 470740

Showing the first eight; more decompositions exist.
