Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522864, here are decompositions:

7 + 522857 = 522864
11 + 522853 = 522864
37 + 522827 = 522864
53 + 522811 = 522864
101 + 522763 = 522864
103 + 522761 = 522864
107 + 522757 = 522864
127 + 522737 = 522864

Showing the first eight; more decompositions exist.
