Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505732, here are decompositions:

5 + 505727 = 505732
23 + 505709 = 505732
41 + 505691 = 505732
89 + 505643 = 505732
113 + 505619 = 505732
131 + 505601 = 505732
173 + 505559 = 505732
239 + 505493 = 505732

Showing the first eight; more decompositions exist.
