Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505876, here are decompositions:

5 + 505871 = 505876
53 + 505823 = 505876
113 + 505763 = 505876
149 + 505727 = 505876
167 + 505709 = 505876
233 + 505643 = 505876
257 + 505619 = 505876
263 + 505613 = 505876

Showing the first eight; more decompositions exist.
