Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601954, here are decompositions:

31 + 31601923 = 31601954
73 + 31601881 = 31601954
211 + 31601743 = 31601954
283 + 31601671 = 31601954
547 + 31601407 = 31601954
607 + 31601347 = 31601954
613 + 31601341 = 31601954
691 + 31601263 = 31601954

Showing the first eight; more decompositions exist.
