Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505750, here are decompositions:

23 + 505727 = 505750
41 + 505709 = 505750
59 + 505691 = 505750
107 + 505643 = 505750
131 + 505619 = 505750
137 + 505613 = 505750
149 + 505601 = 505750
191 + 505559 = 505750

Showing the first eight; more decompositions exist.
