Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594474, here are decompositions:

11 + 31594463 = 31594474
53 + 31594421 = 31594474
101 + 31594373 = 31594474
227 + 31594247 = 31594474
281 + 31594193 = 31594474
311 + 31594163 = 31594474
491 + 31593983 = 31594474
521 + 31593953 = 31594474

Showing the first eight; more decompositions exist.
