Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573916, here are decompositions:

97 + 31573819 = 31573916
163 + 31573753 = 31573916
277 + 31573639 = 31573916
523 + 31573393 = 31573916
727 + 31573189 = 31573916
823 + 31573093 = 31573916
859 + 31573057 = 31573916
937 + 31572979 = 31573916

Showing the first eight; more decompositions exist.
