Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505798, here are decompositions:

17 + 505781 = 505798
71 + 505727 = 505798
89 + 505709 = 505798
107 + 505691 = 505798
179 + 505619 = 505798
191 + 505607 = 505798
197 + 505601 = 505798
239 + 505559 = 505798

Showing the first eight; more decompositions exist.
