Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505422, here are decompositions:

11 + 505411 = 505422
13 + 505409 = 505422
23 + 505399 = 505422
53 + 505369 = 505422
83 + 505339 = 505422
101 + 505321 = 505422
103 + 505319 = 505422
109 + 505313 = 505422

Showing the first eight; more decompositions exist.
