Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594328, here are decompositions:

19 + 31594309 = 31594328
397 + 31593931 = 31594328
541 + 31593787 = 31594328
607 + 31593721 = 31594328
739 + 31593589 = 31594328
757 + 31593571 = 31594328
811 + 31593517 = 31594328
937 + 31593391 = 31594328

Showing the first eight; more decompositions exist.
