Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505310, here are decompositions:

31 + 505279 = 505310
73 + 505237 = 505310
79 + 505231 = 505310
97 + 505213 = 505310
109 + 505201 = 505310
151 + 505159 = 505310
181 + 505129 = 505310
193 + 505117 = 505310

Showing the first eight; more decompositions exist.
