Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622794, here are decompositions:

17 + 31622777 = 31622794
53 + 31622741 = 31622794
101 + 31622693 = 31622794
107 + 31622687 = 31622794
131 + 31622663 = 31622794
257 + 31622537 = 31622794
521 + 31622273 = 31622794
557 + 31622237 = 31622794

Showing the first eight; more decompositions exist.
