Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594294, here are decompositions:

23 + 31594271 = 31594294
47 + 31594247 = 31594294
101 + 31594193 = 31594294
131 + 31594163 = 31594294
197 + 31594097 = 31594294
233 + 31594061 = 31594294
311 + 31593983 = 31594294
461 + 31593833 = 31594294

Showing the first eight; more decompositions exist.
