Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607696, here are decompositions:

7 + 31607689 = 31607696
13 + 31607683 = 31607696
67 + 31607629 = 31607696
97 + 31607599 = 31607696
193 + 31607503 = 31607696
223 + 31607473 = 31607696
397 + 31607299 = 31607696
433 + 31607263 = 31607696

Showing the first eight; more decompositions exist.
