Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585416, here are decompositions:

17 + 31585399 = 31585416
47 + 31585369 = 31585416
73 + 31585343 = 31585416
89 + 31585327 = 31585416
97 + 31585319 = 31585416
103 + 31585313 = 31585416
127 + 31585289 = 31585416
199 + 31585217 = 31585416

Showing the first eight; more decompositions exist.
