Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594564, here are decompositions:

11 + 31594553 = 31594564
17 + 31594547 = 31594564
101 + 31594463 = 31594564
191 + 31594373 = 31594564
233 + 31594331 = 31594564
293 + 31594271 = 31594564
317 + 31594247 = 31594564
401 + 31594163 = 31594564

Showing the first eight; more decompositions exist.
