Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594622, here are decompositions:

13 + 31594609 = 31594622
43 + 31594579 = 31594622
193 + 31594429 = 31594622
223 + 31594399 = 31594622
229 + 31594393 = 31594622
271 + 31594351 = 31594622
313 + 31594309 = 31594622
349 + 31594273 = 31594622

Showing the first eight; more decompositions exist.
