Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505894, here are decompositions:

17 + 505877 = 505894
23 + 505871 = 505894
71 + 505823 = 505894
83 + 505811 = 505894
113 + 505781 = 505894
131 + 505763 = 505894
167 + 505727 = 505894
251 + 505643 = 505894

Showing the first eight; more decompositions exist.
