Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601376, here are decompositions:

17 + 31601359 = 31601376
19 + 31601357 = 31601376
29 + 31601347 = 31601376
109 + 31601267 = 31601376
113 + 31601263 = 31601376
173 + 31601203 = 31601376
197 + 31601179 = 31601376
239 + 31601137 = 31601376

Showing the first eight; more decompositions exist.
