Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505268, here are decompositions:

31 + 505237 = 505268
37 + 505231 = 505268
67 + 505201 = 505268
109 + 505159 = 505268
139 + 505129 = 505268
151 + 505117 = 505268
157 + 505111 = 505268
241 + 505027 = 505268

Showing the first eight; more decompositions exist.
