Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585344, here are decompositions:

5 + 31585339 = 31585344
13 + 31585331 = 31585344
17 + 31585327 = 31585344
31 + 31585313 = 31585344
73 + 31585271 = 31585344
83 + 31585261 = 31585344
127 + 31585217 = 31585344
151 + 31585193 = 31585344

Showing the first eight; more decompositions exist.
