Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585926, here are decompositions:

23 + 31585903 = 31585926
37 + 31585889 = 31585926
89 + 31585837 = 31585926
103 + 31585823 = 31585926
109 + 31585817 = 31585926
149 + 31585777 = 31585926
263 + 31585663 = 31585926
277 + 31585649 = 31585926

Showing the first eight; more decompositions exist.
