Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505884, here are decompositions:

7 + 505877 = 505884
13 + 505871 = 505884
17 + 505867 = 505884
61 + 505823 = 505884
73 + 505811 = 505884
103 + 505781 = 505884
107 + 505777 = 505884
157 + 505727 = 505884

Showing the first eight; more decompositions exist.
