Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585464, here are decompositions:

5 + 31585459 = 31585464
11 + 31585453 = 31585464
13 + 31585451 = 31585464
17 + 31585447 = 31585464
23 + 31585441 = 31585464
103 + 31585361 = 31585464
137 + 31585327 = 31585464
151 + 31585313 = 31585464

Showing the first eight; more decompositions exist.
