Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585506, here are decompositions:

5 + 31585501 = 31585506
13 + 31585493 = 31585506
37 + 31585469 = 31585506
47 + 31585459 = 31585506
53 + 31585453 = 31585506
59 + 31585447 = 31585506
107 + 31585399 = 31585506
137 + 31585369 = 31585506

Showing the first eight; more decompositions exist.
