Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524990, here are decompositions:

23 + 31524967 = 31524990
53 + 31524937 = 31524990
97 + 31524893 = 31524990
127 + 31524863 = 31524990
151 + 31524839 = 31524990
181 + 31524809 = 31524990
193 + 31524797 = 31524990
197 + 31524793 = 31524990

Showing the first eight; more decompositions exist.
