Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472518, here are decompositions:

41 + 472477 = 472518
61 + 472457 = 472518
97 + 472421 = 472518
107 + 472411 = 472518
127 + 472391 = 472518
149 + 472369 = 472518
199 + 472319 = 472518
229 + 472289 = 472518

Showing the first eight; more decompositions exist.
