Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594210, here are decompositions:

17 + 31594193 = 31594210
47 + 31594163 = 31594210
59 + 31594151 = 31594210
113 + 31594097 = 31594210
149 + 31594061 = 31594210
227 + 31593983 = 31594210
251 + 31593959 = 31594210
257 + 31593953 = 31594210

Showing the first eight; more decompositions exist.
