Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601696, here are decompositions:

67 + 31601629 = 31601696
127 + 31601569 = 31601696
157 + 31601539 = 31601696
223 + 31601473 = 31601696
337 + 31601359 = 31601696
349 + 31601347 = 31601696
433 + 31601263 = 31601696
613 + 31601083 = 31601696

Showing the first eight; more decompositions exist.
