Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505316, here are decompositions:

3 + 505313 = 505316
37 + 505279 = 505316
79 + 505237 = 505316
103 + 505213 = 505316
157 + 505159 = 505316
193 + 505123 = 505316
199 + 505117 = 505316
283 + 505033 = 505316

Showing the first eight; more decompositions exist.
