Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601930, here are decompositions:

7 + 31601923 = 31601930
67 + 31601863 = 31601930
163 + 31601767 = 31601930
223 + 31601707 = 31601930
379 + 31601551 = 31601930
421 + 31601509 = 31601930
457 + 31601473 = 31601930
523 + 31601407 = 31601930

Showing the first eight; more decompositions exist.
