Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594330, here are decompositions:

59 + 31594271 = 31594330
83 + 31594247 = 31594330
137 + 31594193 = 31594330
167 + 31594163 = 31594330
179 + 31594151 = 31594330
197 + 31594133 = 31594330
233 + 31594097 = 31594330
269 + 31594061 = 31594330

Showing the first eight; more decompositions exist.
