Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505966, here are decompositions:

5 + 505961 = 505966
17 + 505949 = 505966
47 + 505919 = 505966
59 + 505907 = 505966
89 + 505877 = 505966
239 + 505727 = 505966
257 + 505709 = 505966
347 + 505619 = 505966

Showing the first eight; more decompositions exist.
