Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524822, here are decompositions:

13 + 31524809 = 31524822
29 + 31524793 = 31524822
31 + 31524791 = 31524822
59 + 31524763 = 31524822
101 + 31524721 = 31524822
149 + 31524673 = 31524822
179 + 31524643 = 31524822
181 + 31524641 = 31524822

Showing the first eight; more decompositions exist.
