Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505320, here are decompositions:

7 + 505313 = 505320
19 + 505301 = 505320
37 + 505283 = 505320
41 + 505279 = 505320
43 + 505277 = 505320
83 + 505237 = 505320
89 + 505231 = 505320
107 + 505213 = 505320

Showing the first eight; more decompositions exist.
