Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505950, here are decompositions:

23 + 505927 = 505950
31 + 505919 = 505950
43 + 505907 = 505950
73 + 505877 = 505950
79 + 505871 = 505950
83 + 505867 = 505950
127 + 505823 = 505950
131 + 505819 = 505950

Showing the first eight; more decompositions exist.
