Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505756, here are decompositions:

29 + 505727 = 505756
47 + 505709 = 505756
113 + 505643 = 505756
137 + 505619 = 505756
149 + 505607 = 505756
197 + 505559 = 505756
233 + 505523 = 505756
263 + 505493 = 505756

Showing the first eight; more decompositions exist.
