Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522138, here are decompositions:

11 + 522127 = 522138
59 + 522079 = 522138
79 + 522059 = 522138
101 + 522037 = 522138
139 + 521999 = 522138
157 + 521981 = 522138
241 + 521897 = 522138
251 + 521887 = 522138

Showing the first eight; more decompositions exist.
