Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520312, here are decompositions:

3 + 520309 = 520312
5 + 520307 = 520312
71 + 520241 = 520312
239 + 520073 = 520312
269 + 520043 = 520312
281 + 520031 = 520312
293 + 520019 = 520312
389 + 519923 = 520312

Showing the first eight; more decompositions exist.
