Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472638, here are decompositions:

7 + 472631 = 472638
41 + 472597 = 472638
79 + 472559 = 472638
97 + 472541 = 472638
181 + 472457 = 472638
227 + 472411 = 472638
239 + 472399 = 472638
269 + 472369 = 472638

Showing the first eight; more decompositions exist.
