Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601360, here are decompositions:

3 + 31601357 = 31601360
13 + 31601347 = 31601360
19 + 31601341 = 31601360
97 + 31601263 = 31601360
157 + 31601203 = 31601360
181 + 31601179 = 31601360
223 + 31601137 = 31601360
277 + 31601083 = 31601360

Showing the first eight; more decompositions exist.
