Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505412, here are decompositions:

3 + 505409 = 505412
13 + 505399 = 505412
43 + 505369 = 505412
73 + 505339 = 505412
181 + 505231 = 505412
199 + 505213 = 505412
211 + 505201 = 505412
283 + 505129 = 505412

Showing the first eight; more decompositions exist.
