Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585352, here are decompositions:

13 + 31585339 = 31585352
163 + 31585189 = 31585352
181 + 31585171 = 31585352
193 + 31585159 = 31585352
499 + 31584853 = 31585352
523 + 31584829 = 31585352
739 + 31584613 = 31585352
751 + 31584601 = 31585352

Showing the first eight; more decompositions exist.
