Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585466, here are decompositions:

7 + 31585459 = 31585466
13 + 31585453 = 31585466
19 + 31585447 = 31585466
67 + 31585399 = 31585466
97 + 31585369 = 31585466
127 + 31585339 = 31585466
139 + 31585327 = 31585466
277 + 31585189 = 31585466

Showing the first eight; more decompositions exist.
