Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523186, here are decompositions:

17 + 523169 = 523186
89 + 523097 = 523186
137 + 523049 = 523186
179 + 523007 = 523186
197 + 522989 = 523186
227 + 522959 = 523186
239 + 522947 = 523186
347 + 522839 = 523186

Showing the first eight; more decompositions exist.
