Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520666, here are decompositions:

17 + 520649 = 520666
59 + 520607 = 520666
137 + 520529 = 520666
233 + 520433 = 520666
239 + 520427 = 520666
257 + 520409 = 520666
317 + 520349 = 520666
353 + 520313 = 520666

Showing the first eight; more decompositions exist.
