Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601914, here are decompositions:

17 + 31601897 = 31601914
23 + 31601891 = 31601914
41 + 31601873 = 31601914
131 + 31601783 = 31601914
191 + 31601723 = 31601914
263 + 31601651 = 31601914
347 + 31601567 = 31601914
401 + 31601513 = 31601914

Showing the first eight; more decompositions exist.
