Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594982, here are decompositions:

19 + 31594963 = 31594982
79 + 31594903 = 31594982
109 + 31594873 = 31594982
283 + 31594699 = 31594982
373 + 31594609 = 31594982
409 + 31594573 = 31594982
631 + 31594351 = 31594982
673 + 31594309 = 31594982

Showing the first eight; more decompositions exist.
