Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594476, here are decompositions:

13 + 31594463 = 31594476
47 + 31594429 = 31594476
83 + 31594393 = 31594476
103 + 31594373 = 31594476
167 + 31594309 = 31594476
229 + 31594247 = 31594476
239 + 31594237 = 31594476
283 + 31594193 = 31594476

Showing the first eight; more decompositions exist.
