Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594372, here are decompositions:

41 + 31594331 = 31594372
101 + 31594271 = 31594372
179 + 31594193 = 31594372
239 + 31594133 = 31594372
311 + 31594061 = 31594372
389 + 31593983 = 31594372
419 + 31593953 = 31594372
503 + 31593869 = 31594372

Showing the first eight; more decompositions exist.
