Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505758, here are decompositions:

31 + 505727 = 505758
47 + 505711 = 505758
67 + 505691 = 505758
89 + 505669 = 505758
101 + 505657 = 505758
139 + 505619 = 505758
151 + 505607 = 505758
157 + 505601 = 505758

Showing the first eight; more decompositions exist.
