Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524846, here are decompositions:

7 + 31524839 = 31524846
37 + 31524809 = 31524846
53 + 31524793 = 31524846
79 + 31524767 = 31524846
83 + 31524763 = 31524846
173 + 31524673 = 31524846
239 + 31524607 = 31524846
277 + 31524569 = 31524846

Showing the first eight; more decompositions exist.
