Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585362, here are decompositions:

19 + 31585343 = 31585362
23 + 31585339 = 31585362
31 + 31585331 = 31585362
43 + 31585319 = 31585362
73 + 31585289 = 31585362
101 + 31585261 = 31585362
163 + 31585199 = 31585362
173 + 31585189 = 31585362

Showing the first eight; more decompositions exist.
