Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594396, here are decompositions:

3 + 31594393 = 31594396
23 + 31594373 = 31594396
149 + 31594247 = 31594396
233 + 31594163 = 31594396
263 + 31594133 = 31594396
347 + 31594049 = 31594396
443 + 31593953 = 31594396
557 + 31593839 = 31594396

Showing the first eight; more decompositions exist.
