Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524750, here are decompositions:

29 + 31524721 = 31524750
73 + 31524677 = 31524750
107 + 31524643 = 31524750
109 + 31524641 = 31524750
163 + 31524587 = 31524750
181 + 31524569 = 31524750
227 + 31524523 = 31524750
233 + 31524517 = 31524750

Showing the first eight; more decompositions exist.
