Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585348, here are decompositions:

5 + 31585343 = 31585348
17 + 31585331 = 31585348
29 + 31585319 = 31585348
59 + 31585289 = 31585348
131 + 31585217 = 31585348
149 + 31585199 = 31585348
167 + 31585181 = 31585348
269 + 31585079 = 31585348

Showing the first eight; more decompositions exist.
