Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490472, here are decompositions:

13 + 490459 = 490472
19 + 490453 = 490472
79 + 490393 = 490472
163 + 490309 = 490472
223 + 490249 = 490472
271 + 490201 = 490472
313 + 490159 = 490472
439 + 490033 = 490472

Showing the first eight; more decompositions exist.
