Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524824, here are decompositions:

31 + 31524793 = 31524824
61 + 31524763 = 31524824
103 + 31524721 = 31524824
151 + 31524673 = 31524824
181 + 31524643 = 31524824
283 + 31524541 = 31524824
307 + 31524517 = 31524824
421 + 31524403 = 31524824

Showing the first eight; more decompositions exist.
