Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607694, here are decompositions:

5 + 31607689 = 31607694
7 + 31607687 = 31607694
11 + 31607683 = 31607694
23 + 31607671 = 31607694
113 + 31607581 = 31607694
163 + 31607531 = 31607694
191 + 31607503 = 31607694
233 + 31607461 = 31607694

Showing the first eight; more decompositions exist.
