Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524964, here are decompositions:

71 + 31524893 = 31524964
101 + 31524863 = 31524964
167 + 31524797 = 31524964
173 + 31524791 = 31524964
197 + 31524767 = 31524964
431 + 31524533 = 31524964
797 + 31524167 = 31524964
857 + 31524107 = 31524964

Showing the first eight; more decompositions exist.
