Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607914, here are decompositions:

5 + 31607909 = 31607914
11 + 31607903 = 31607914
17 + 31607897 = 31607914
47 + 31607867 = 31607914
83 + 31607831 = 31607914
131 + 31607783 = 31607914
167 + 31607747 = 31607914
197 + 31607717 = 31607914

Showing the first eight; more decompositions exist.
