Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601932, here are decompositions:

41 + 31601891 = 31601932
59 + 31601873 = 31601932
83 + 31601849 = 31601932
113 + 31601819 = 31601932
149 + 31601783 = 31601932
233 + 31601699 = 31601932
281 + 31601651 = 31601932
419 + 31601513 = 31601932

Showing the first eight; more decompositions exist.
