Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505382, here are decompositions:

13 + 505369 = 505382
43 + 505339 = 505382
61 + 505321 = 505382
103 + 505279 = 505382
151 + 505231 = 505382
181 + 505201 = 505382
223 + 505159 = 505382
271 + 505111 = 505382

Showing the first eight; more decompositions exist.
