Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522172, here are decompositions:

5 + 522167 = 522172
11 + 522161 = 522172
59 + 522113 = 522172
89 + 522083 = 522172
113 + 522059 = 522172
173 + 521999 = 522172
179 + 521993 = 522172
191 + 521981 = 522172

Showing the first eight; more decompositions exist.
