Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524910, here are decompositions:

17 + 31524893 = 31524910
47 + 31524863 = 31524910
71 + 31524839 = 31524910
101 + 31524809 = 31524910
113 + 31524797 = 31524910
233 + 31524677 = 31524910
269 + 31524641 = 31524910
401 + 31524509 = 31524910

Showing the first eight; more decompositions exist.
