Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598794, here are decompositions:

5 + 31598789 = 31598794
11 + 31598783 = 31598794
23 + 31598771 = 31598794
41 + 31598753 = 31598794
107 + 31598687 = 31598794
251 + 31598543 = 31598794
257 + 31598537 = 31598794
281 + 31598513 = 31598794

Showing the first eight; more decompositions exist.
