Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522178, here are decompositions:

11 + 522167 = 522178
17 + 522161 = 522178
131 + 522047 = 522178
179 + 521999 = 522178
197 + 521981 = 522178
281 + 521897 = 522178
317 + 521861 = 522178
347 + 521831 = 522178

Showing the first eight; more decompositions exist.
