Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607874, here are decompositions:

5 + 31607869 = 31607874
7 + 31607867 = 31607874
17 + 31607857 = 31607874
43 + 31607831 = 31607874
83 + 31607791 = 31607874
127 + 31607747 = 31607874
157 + 31607717 = 31607874
191 + 31607683 = 31607874

Showing the first eight; more decompositions exist.
