Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601962, here are decompositions:

71 + 31601891 = 31601962
89 + 31601873 = 31601962
113 + 31601849 = 31601962
179 + 31601783 = 31601962
239 + 31601723 = 31601962
251 + 31601711 = 31601962
263 + 31601699 = 31601962
311 + 31601651 = 31601962

Showing the first eight; more decompositions exist.
