Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505406, here are decompositions:

7 + 505399 = 505406
37 + 505369 = 505406
67 + 505339 = 505406
79 + 505327 = 505406
127 + 505279 = 505406
193 + 505213 = 505406
277 + 505129 = 505406
283 + 505123 = 505406

Showing the first eight; more decompositions exist.
