Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505726, here are decompositions:

17 + 505709 = 505726
83 + 505643 = 505726
107 + 505619 = 505726
113 + 505613 = 505726
167 + 505559 = 505726
233 + 505493 = 505726
257 + 505469 = 505726
317 + 505409 = 505726

Showing the first eight; more decompositions exist.
