Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505338, here are decompositions:

11 + 505327 = 505338
17 + 505321 = 505338
19 + 505319 = 505338
37 + 505301 = 505338
59 + 505279 = 505338
61 + 505277 = 505338
101 + 505237 = 505338
107 + 505231 = 505338

Showing the first eight; more decompositions exist.
