Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505854, here are decompositions:

31 + 505823 = 505854
43 + 505811 = 505854
73 + 505781 = 505854
127 + 505727 = 505854
163 + 505691 = 505854
191 + 505663 = 505854
197 + 505657 = 505854
211 + 505643 = 505854

Showing the first eight; more decompositions exist.
