Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470686, here are decompositions:

17 + 470669 = 470686
23 + 470663 = 470686
59 + 470627 = 470686
89 + 470597 = 470686
107 + 470579 = 470686
173 + 470513 = 470686
197 + 470489 = 470686
233 + 470453 = 470686

Showing the first eight; more decompositions exist.
