Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601366, here are decompositions:

7 + 31601359 = 31601366
19 + 31601347 = 31601366
103 + 31601263 = 31601366
163 + 31601203 = 31601366
229 + 31601137 = 31601366
283 + 31601083 = 31601366
373 + 31600993 = 31601366
397 + 31600969 = 31601366

Showing the first eight; more decompositions exist.
