Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505774, here are decompositions:

11 + 505763 = 505774
47 + 505727 = 505774
83 + 505691 = 505774
131 + 505643 = 505774
167 + 505607 = 505774
173 + 505601 = 505774
251 + 505523 = 505774
263 + 505511 = 505774

Showing the first eight; more decompositions exist.
