Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469490, here are decompositions:

3 + 469487 = 469490
61 + 469429 = 469490
79 + 469411 = 469490
127 + 469363 = 469490
139 + 469351 = 469490
211 + 469279 = 469490
223 + 469267 = 469490
271 + 469219 = 469490

Showing the first eight; more decompositions exist.
