Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571962, here are decompositions:

5 + 31571957 = 31571962
83 + 31571879 = 31571962
113 + 31571849 = 31571962
263 + 31571699 = 31571962
311 + 31571651 = 31571962
509 + 31571453 = 31571962
563 + 31571399 = 31571962
659 + 31571303 = 31571962

Showing the first eight; more decompositions exist.
