Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594338, here are decompositions:

5 + 31594333 = 31594338
7 + 31594331 = 31594338
29 + 31594309 = 31594338
67 + 31594271 = 31594338
101 + 31594237 = 31594338
179 + 31594159 = 31594338
241 + 31594097 = 31594338
257 + 31594081 = 31594338

Showing the first eight; more decompositions exist.
