Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585496, here are decompositions:

3 + 31585493 = 31585496
37 + 31585459 = 31585496
43 + 31585453 = 31585496
97 + 31585399 = 31585496
127 + 31585369 = 31585496
157 + 31585339 = 31585496
307 + 31585189 = 31585496
337 + 31585159 = 31585496

Showing the first eight; more decompositions exist.
