Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601474, here are decompositions:

67 + 31601407 = 31601474
127 + 31601347 = 31601474
211 + 31601263 = 31601474
271 + 31601203 = 31601474
283 + 31601191 = 31601474
337 + 31601137 = 31601474
397 + 31601077 = 31601474
433 + 31601041 = 31601474

Showing the first eight; more decompositions exist.
