Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601924, here are decompositions:

43 + 31601881 = 31601924
61 + 31601863 = 31601924
157 + 31601767 = 31601924
181 + 31601743 = 31601924
373 + 31601551 = 31601924
397 + 31601527 = 31601924
577 + 31601347 = 31601924
661 + 31601263 = 31601924

Showing the first eight; more decompositions exist.
