Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580794, here are decompositions:

5 + 31580789 = 31580794
53 + 31580741 = 31580794
83 + 31580711 = 31580794
101 + 31580693 = 31580794
107 + 31580687 = 31580794
173 + 31580621 = 31580794
263 + 31580531 = 31580794
293 + 31580501 = 31580794

Showing the first eight; more decompositions exist.
