Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601364, here are decompositions:

5 + 31601359 = 31601364
7 + 31601357 = 31601364
17 + 31601347 = 31601364
23 + 31601341 = 31601364
97 + 31601267 = 31601364
101 + 31601263 = 31601364
173 + 31601191 = 31601364
227 + 31601137 = 31601364

Showing the first eight; more decompositions exist.
