Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585896, here are decompositions:

7 + 31585889 = 31585896
47 + 31585849 = 31585896
59 + 31585837 = 31585896
73 + 31585823 = 31585896
79 + 31585817 = 31585896
113 + 31585783 = 31585896
229 + 31585667 = 31585896
233 + 31585663 = 31585896

Showing the first eight; more decompositions exist.
