Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505516, here are decompositions:

3 + 505513 = 505516
5 + 505511 = 505516
23 + 505493 = 505516
47 + 505469 = 505516
107 + 505409 = 505516
149 + 505367 = 505516
197 + 505319 = 505516
233 + 505283 = 505516

Showing the first eight; more decompositions exist.
