Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520546, here are decompositions:

17 + 520529 = 520546
113 + 520433 = 520546
137 + 520409 = 520546
167 + 520379 = 520546
197 + 520349 = 520546
233 + 520313 = 520546
239 + 520307 = 520546
353 + 520193 = 520546

Showing the first eight; more decompositions exist.
