Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505970, here are decompositions:

43 + 505927 = 505970
103 + 505867 = 505970
151 + 505819 = 505970
193 + 505777 = 505970
211 + 505759 = 505970
277 + 505693 = 505970
307 + 505663 = 505970
313 + 505657 = 505970

Showing the first eight; more decompositions exist.
