Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505306, here are decompositions:

5 + 505301 = 505306
23 + 505283 = 505306
29 + 505277 = 505306
149 + 505157 = 505306
167 + 505139 = 505306
233 + 505073 = 505306
239 + 505067 = 505306
257 + 505049 = 505306

Showing the first eight; more decompositions exist.
