Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585706, here are decompositions:

43 + 31585663 = 31585706
109 + 31585597 = 31585706
127 + 31585579 = 31585706
157 + 31585549 = 31585706
307 + 31585399 = 31585706
337 + 31585369 = 31585706
367 + 31585339 = 31585706
379 + 31585327 = 31585706

Showing the first eight; more decompositions exist.
