Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505738, here are decompositions:

11 + 505727 = 505738
29 + 505709 = 505738
47 + 505691 = 505738
131 + 505607 = 505738
137 + 505601 = 505738
179 + 505559 = 505738
227 + 505511 = 505738
257 + 505481 = 505738

Showing the first eight; more decompositions exist.
