Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594276, here are decompositions:

3 + 31594273 = 31594276
5 + 31594271 = 31594276
29 + 31594247 = 31594276
83 + 31594193 = 31594276
113 + 31594163 = 31594276
179 + 31594097 = 31594276
227 + 31594049 = 31594276
293 + 31593983 = 31594276

Showing the first eight; more decompositions exist.
