Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524976, here are decompositions:

83 + 31524893 = 31524976
113 + 31524863 = 31524976
137 + 31524839 = 31524976
167 + 31524809 = 31524976
179 + 31524797 = 31524976
389 + 31524587 = 31524976
443 + 31524533 = 31524976
467 + 31524509 = 31524976

Showing the first eight; more decompositions exist.
