Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524862, here are decompositions:

23 + 31524839 = 31524862
53 + 31524809 = 31524862
71 + 31524791 = 31524862
293 + 31524569 = 31524862
353 + 31524509 = 31524862
443 + 31524419 = 31524862
569 + 31524293 = 31524862
701 + 31524161 = 31524862

Showing the first eight; more decompositions exist.
