Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594442, here are decompositions:

13 + 31594429 = 31594442
43 + 31594399 = 31594442
109 + 31594333 = 31594442
283 + 31594159 = 31594442
379 + 31594063 = 31594442
499 + 31593943 = 31594442
541 + 31593901 = 31594442
739 + 31593703 = 31594442

Showing the first eight; more decompositions exist.
