Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594298, here are decompositions:

61 + 31594237 = 31594298
139 + 31594159 = 31594298
367 + 31593931 = 31594298
397 + 31593901 = 31594298
577 + 31593721 = 31594298
691 + 31593607 = 31594298
709 + 31593589 = 31594298
727 + 31593571 = 31594298

Showing the first eight; more decompositions exist.
