Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599696, here are decompositions:

13 + 31599683 = 31599696
43 + 31599653 = 31599696
47 + 31599649 = 31599696
67 + 31599629 = 31599696
97 + 31599599 = 31599696
197 + 31599499 = 31599696
257 + 31599439 = 31599696
307 + 31599389 = 31599696

Showing the first eight; more decompositions exist.
