Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505882, here are decompositions:

5 + 505877 = 505882
11 + 505871 = 505882
59 + 505823 = 505882
71 + 505811 = 505882
101 + 505781 = 505882
173 + 505709 = 505882
191 + 505691 = 505882
239 + 505643 = 505882

Showing the first eight; more decompositions exist.
