Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601036, here are decompositions:

13 + 31601023 = 31601036
43 + 31600993 = 31601036
67 + 31600969 = 31601036
79 + 31600957 = 31601036
193 + 31600843 = 31601036
283 + 31600753 = 31601036
367 + 31600669 = 31601036
373 + 31600663 = 31601036

Showing the first eight; more decompositions exist.
