Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524732, here are decompositions:

11 + 31524721 = 31524732
59 + 31524673 = 31524732
89 + 31524643 = 31524732
163 + 31524569 = 31524732
191 + 31524541 = 31524732
199 + 31524533 = 31524732
223 + 31524509 = 31524732
233 + 31524499 = 31524732

Showing the first eight; more decompositions exist.
