Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585326, here are decompositions:

7 + 31585319 = 31585326
13 + 31585313 = 31585326
37 + 31585289 = 31585326
109 + 31585217 = 31585326
127 + 31585199 = 31585326
137 + 31585189 = 31585326
167 + 31585159 = 31585326
233 + 31585093 = 31585326

Showing the first eight; more decompositions exist.
