Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594028, here are decompositions:

97 + 31593931 = 31594028
127 + 31593901 = 31594028
241 + 31593787 = 31594028
307 + 31593721 = 31594028
397 + 31593631 = 31594028
421 + 31593607 = 31594028
439 + 31593589 = 31594028
457 + 31593571 = 31594028

Showing the first eight; more decompositions exist.
