Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505446, here are decompositions:

17 + 505429 = 505446
37 + 505409 = 505446
47 + 505399 = 505446
79 + 505367 = 505446
89 + 505357 = 505446
107 + 505339 = 505446
127 + 505319 = 505446
163 + 505283 = 505446

Showing the first eight; more decompositions exist.
