Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601508, here are decompositions:

19 + 31601489 = 31601508
97 + 31601411 = 31601508
101 + 31601407 = 31601508
149 + 31601359 = 31601508
151 + 31601357 = 31601508
167 + 31601341 = 31601508
241 + 31601267 = 31601508
317 + 31601191 = 31601508

Showing the first eight; more decompositions exist.
