Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585350, here are decompositions:

7 + 31585343 = 31585350
11 + 31585339 = 31585350
19 + 31585331 = 31585350
23 + 31585327 = 31585350
31 + 31585319 = 31585350
37 + 31585313 = 31585350
61 + 31585289 = 31585350
79 + 31585271 = 31585350

Showing the first eight; more decompositions exist.
