Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594112, here are decompositions:

31 + 31594081 = 31594112
73 + 31594039 = 31594112
181 + 31593931 = 31594112
211 + 31593901 = 31594112
349 + 31593763 = 31594112
409 + 31593703 = 31594112
499 + 31593613 = 31594112
523 + 31593589 = 31594112

Showing the first eight; more decompositions exist.
