Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601894, here are decompositions:

3 + 31601891 = 31601894
13 + 31601881 = 31601894
31 + 31601863 = 31601894
127 + 31601767 = 31601894
151 + 31601743 = 31601894
223 + 31601671 = 31601894
367 + 31601527 = 31601894
421 + 31601473 = 31601894

Showing the first eight; more decompositions exist.
