Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522180, here are decompositions:

13 + 522167 = 522180
19 + 522161 = 522180
23 + 522157 = 522180
53 + 522127 = 522180
67 + 522113 = 522180
97 + 522083 = 522180
101 + 522079 = 522180
107 + 522073 = 522180

Showing the first eight; more decompositions exist.
