Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601804, here are decompositions:

37 + 31601767 = 31601804
61 + 31601743 = 31601804
97 + 31601707 = 31601804
277 + 31601527 = 31601804
331 + 31601473 = 31601804
397 + 31601407 = 31601804
457 + 31601347 = 31601804
463 + 31601341 = 31601804

Showing the first eight; more decompositions exist.
