Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594374, here are decompositions:

23 + 31594351 = 31594374
41 + 31594333 = 31594374
43 + 31594331 = 31594374
101 + 31594273 = 31594374
103 + 31594271 = 31594374
127 + 31594247 = 31594374
137 + 31594237 = 31594374
181 + 31594193 = 31594374

Showing the first eight; more decompositions exist.
