Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505930, here are decompositions:

3 + 505927 = 505930
11 + 505919 = 505930
23 + 505907 = 505930
53 + 505877 = 505930
59 + 505871 = 505930
107 + 505823 = 505930
149 + 505781 = 505930
167 + 505763 = 505930

Showing the first eight; more decompositions exist.
