Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585794, here are decompositions:

11 + 31585783 = 31585794
13 + 31585781 = 31585794
17 + 31585777 = 31585794
43 + 31585751 = 31585794
103 + 31585691 = 31585794
127 + 31585667 = 31585794
131 + 31585663 = 31585794
157 + 31585637 = 31585794

Showing the first eight; more decompositions exist.
