Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522166, here are decompositions:

5 + 522161 = 522166
53 + 522113 = 522166
83 + 522083 = 522166
107 + 522059 = 522166
149 + 522017 = 522166
167 + 521999 = 522166
173 + 521993 = 522166
263 + 521903 = 522166

Showing the first eight; more decompositions exist.
