Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522972, here are decompositions:

11 + 522961 = 522972
13 + 522959 = 522972
29 + 522943 = 522972
53 + 522919 = 522972
89 + 522883 = 522972
101 + 522871 = 522972
211 + 522761 = 522972
223 + 522749 = 522972

Showing the first eight; more decompositions exist.
