Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585562, here are decompositions:

13 + 31585549 = 31585562
61 + 31585501 = 31585562
103 + 31585459 = 31585562
109 + 31585453 = 31585562
163 + 31585399 = 31585562
193 + 31585369 = 31585562
223 + 31585339 = 31585562
373 + 31585189 = 31585562

Showing the first eight; more decompositions exist.
