Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522918, here are decompositions:

31 + 522887 = 522918
37 + 522881 = 522918
47 + 522871 = 522918
61 + 522857 = 522918
79 + 522839 = 522918
89 + 522829 = 522918
107 + 522811 = 522918
131 + 522787 = 522918

Showing the first eight; more decompositions exist.
