Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594274, here are decompositions:

3 + 31594271 = 31594274
37 + 31594237 = 31594274
193 + 31594081 = 31594274
211 + 31594063 = 31594274
331 + 31593943 = 31594274
337 + 31593937 = 31594274
373 + 31593901 = 31594274
487 + 31593787 = 31594274

Showing the first eight; more decompositions exist.
