Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505490, here are decompositions:

31 + 505459 = 505490
43 + 505447 = 505490
61 + 505429 = 505490
79 + 505411 = 505490
151 + 505339 = 505490
163 + 505327 = 505490
211 + 505279 = 505490
277 + 505213 = 505490

Showing the first eight; more decompositions exist.
