Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585482, here are decompositions:

13 + 31585469 = 31585482
23 + 31585459 = 31585482
29 + 31585453 = 31585482
31 + 31585451 = 31585482
41 + 31585441 = 31585482
83 + 31585399 = 31585482
113 + 31585369 = 31585482
139 + 31585343 = 31585482

Showing the first eight; more decompositions exist.
