Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497934, here are decompositions:

3 + 31497931 = 31497934
5 + 31497929 = 31497934
71 + 31497863 = 31497934
107 + 31497827 = 31497934
131 + 31497803 = 31497934
137 + 31497797 = 31497934
197 + 31497737 = 31497934
227 + 31497707 = 31497934

Showing the first eight; more decompositions exist.
