Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505308, here are decompositions:

7 + 505301 = 505308
29 + 505279 = 505308
31 + 505277 = 505308
71 + 505237 = 505308
107 + 505201 = 505308
127 + 505181 = 505308
149 + 505159 = 505308
151 + 505157 = 505308

Showing the first eight; more decompositions exist.
