Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505906, here are decompositions:

29 + 505877 = 505906
83 + 505823 = 505906
179 + 505727 = 505906
197 + 505709 = 505906
263 + 505643 = 505906
293 + 505613 = 505906
347 + 505559 = 505906
383 + 505523 = 505906

Showing the first eight; more decompositions exist.
