Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505912, here are decompositions:

5 + 505907 = 505912
41 + 505871 = 505912
89 + 505823 = 505912
101 + 505811 = 505912
131 + 505781 = 505912
149 + 505763 = 505912
269 + 505643 = 505912
293 + 505619 = 505912

Showing the first eight; more decompositions exist.
