Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585098, here are decompositions:

5 + 31585093 = 31585098
19 + 31585079 = 31585098
31 + 31585067 = 31585098
37 + 31585061 = 31585098
79 + 31585019 = 31585098
131 + 31584967 = 31585098
137 + 31584961 = 31585098
151 + 31584947 = 31585098

Showing the first eight; more decompositions exist.
