Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522126, here are decompositions:

13 + 522113 = 522126
43 + 522083 = 522126
47 + 522079 = 522126
53 + 522073 = 522126
67 + 522059 = 522126
79 + 522047 = 522126
89 + 522037 = 522126
109 + 522017 = 522126

Showing the first eight; more decompositions exist.
