Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601594, here are decompositions:

43 + 31601551 = 31601594
67 + 31601527 = 31601594
331 + 31601263 = 31601594
457 + 31601137 = 31601594
571 + 31601023 = 31601594
601 + 31600993 = 31601594
733 + 31600861 = 31601594
751 + 31600843 = 31601594

Showing the first eight; more decompositions exist.
