Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601814, here are decompositions:

5 + 31601809 = 31601814
31 + 31601783 = 31601814
47 + 31601767 = 31601814
71 + 31601743 = 31601814
103 + 31601711 = 31601814
107 + 31601707 = 31601814
163 + 31601651 = 31601814
263 + 31601551 = 31601814

Showing the first eight; more decompositions exist.
