Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472490, here are decompositions:

13 + 472477 = 472490
79 + 472411 = 472490
97 + 472393 = 472490
157 + 472333 = 472490
181 + 472309 = 472490
229 + 472261 = 472490
241 + 472249 = 472490
331 + 472159 = 472490

Showing the first eight; more decompositions exist.
