Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601370, here are decompositions:

11 + 31601359 = 31601370
13 + 31601357 = 31601370
23 + 31601347 = 31601370
29 + 31601341 = 31601370
103 + 31601267 = 31601370
107 + 31601263 = 31601370
167 + 31601203 = 31601370
179 + 31601191 = 31601370

Showing the first eight; more decompositions exist.
