Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524726, here are decompositions:

5 + 31524721 = 31524726
53 + 31524673 = 31524726
83 + 31524643 = 31524726
139 + 31524587 = 31524726
157 + 31524569 = 31524726
193 + 31524533 = 31524726
227 + 31524499 = 31524726
257 + 31524469 = 31524726

Showing the first eight; more decompositions exist.
