Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472540, here are decompositions:

17 + 472523 = 472540
71 + 472469 = 472540
83 + 472457 = 472540
149 + 472391 = 472540
191 + 472349 = 472540
239 + 472301 = 472540
251 + 472289 = 472540
293 + 472247 = 472540

Showing the first eight; more decompositions exist.
