Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589796, here are decompositions:

19 + 31589777 = 31589796
23 + 31589773 = 31589796
37 + 31589759 = 31589796
59 + 31589737 = 31589796
89 + 31589707 = 31589796
103 + 31589693 = 31589796
113 + 31589683 = 31589796
137 + 31589659 = 31589796

Showing the first eight; more decompositions exist.
