Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601352, here are decompositions:

5 + 31601347 = 31601352
11 + 31601341 = 31601352
89 + 31601263 = 31601352
149 + 31601203 = 31601352
173 + 31601179 = 31601352
269 + 31601083 = 31601352
311 + 31601041 = 31601352
359 + 31600993 = 31601352

Showing the first eight; more decompositions exist.
