Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520888, here are decompositions:

47 + 520841 = 520888
101 + 520787 = 520888
167 + 520721 = 520888
197 + 520691 = 520888
239 + 520649 = 520888
257 + 520631 = 520888
281 + 520607 = 520888
317 + 520571 = 520888

Showing the first eight; more decompositions exist.
