Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594904, here are decompositions:

31 + 31594873 = 31594904
37 + 31594867 = 31594904
43 + 31594861 = 31594904
97 + 31594807 = 31594904
157 + 31594747 = 31594904
223 + 31594681 = 31594904
277 + 31594627 = 31594904
307 + 31594597 = 31594904

Showing the first eight; more decompositions exist.
