Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585246, here are decompositions:

29 + 31585217 = 31585246
47 + 31585199 = 31585246
53 + 31585193 = 31585246
107 + 31585139 = 31585246
167 + 31585079 = 31585246
179 + 31585067 = 31585246
227 + 31585019 = 31585246
293 + 31584953 = 31585246

Showing the first eight; more decompositions exist.
