Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594000, here are decompositions:

17 + 31593983 = 31594000
41 + 31593959 = 31594000
47 + 31593953 = 31594000
131 + 31593869 = 31594000
167 + 31593833 = 31594000
233 + 31593767 = 31594000
281 + 31593719 = 31594000
311 + 31593689 = 31594000

Showing the first eight; more decompositions exist.
