Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505226, here are decompositions:

13 + 505213 = 505226
67 + 505159 = 505226
97 + 505129 = 505226
103 + 505123 = 505226
109 + 505117 = 505226
193 + 505033 = 505226
199 + 505027 = 505226
283 + 504943 = 505226

Showing the first eight; more decompositions exist.
