Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523126, here are decompositions:

17 + 523109 = 523126
29 + 523097 = 523126
137 + 522989 = 523126
167 + 522959 = 523126
179 + 522947 = 523126
239 + 522887 = 523126
269 + 522857 = 523126
389 + 522737 = 523126

Showing the first eight; more decompositions exist.
