Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594748, here are decompositions:

19 + 31594729 = 31594748
67 + 31594681 = 31594748
139 + 31594609 = 31594748
151 + 31594597 = 31594748
349 + 31594399 = 31594748
397 + 31594351 = 31594748
439 + 31594309 = 31594748
709 + 31594039 = 31594748

Showing the first eight; more decompositions exist.
