Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601764, here are decompositions:

41 + 31601723 = 31601764
53 + 31601711 = 31601764
113 + 31601651 = 31601764
197 + 31601567 = 31601764
251 + 31601513 = 31601764
347 + 31601417 = 31601764
353 + 31601411 = 31601764
881 + 31600883 = 31601764

Showing the first eight; more decompositions exist.
