Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522154, here are decompositions:

41 + 522113 = 522154
71 + 522083 = 522154
107 + 522047 = 522154
137 + 522017 = 522154
173 + 521981 = 522154
251 + 521903 = 522154
257 + 521897 = 522154
293 + 521861 = 522154

Showing the first eight; more decompositions exist.
