Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599794, here are decompositions:

13 + 31599781 = 31599794
67 + 31599727 = 31599794
241 + 31599553 = 31599794
307 + 31599487 = 31599794
487 + 31599307 = 31599794
547 + 31599247 = 31599794
601 + 31599193 = 31599794
691 + 31599103 = 31599794

Showing the first eight; more decompositions exist.
