Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601996, here are decompositions:

73 + 31601923 = 31601996
229 + 31601767 = 31601996
367 + 31601629 = 31601996
457 + 31601539 = 31601996
487 + 31601509 = 31601996
523 + 31601473 = 31601996
733 + 31601263 = 31601996
859 + 31601137 = 31601996

Showing the first eight; more decompositions exist.
