Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523156, here are decompositions:

47 + 523109 = 523156
59 + 523097 = 523156
107 + 523049 = 523156
149 + 523007 = 523156
167 + 522989 = 523156
197 + 522959 = 523156
269 + 522887 = 523156
317 + 522839 = 523156

Showing the first eight; more decompositions exist.
