Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601966, here are decompositions:

43 + 31601923 = 31601966
103 + 31601863 = 31601966
157 + 31601809 = 31601966
199 + 31601767 = 31601966
223 + 31601743 = 31601966
337 + 31601629 = 31601966
397 + 31601569 = 31601966
439 + 31601527 = 31601966

Showing the first eight; more decompositions exist.
