Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607474, here are decompositions:

13 + 31607461 = 31607474
181 + 31607293 = 31607474
193 + 31607281 = 31607474
211 + 31607263 = 31607474
337 + 31607137 = 31607474
373 + 31607101 = 31607474
523 + 31606951 = 31607474
571 + 31606903 = 31607474

Showing the first eight; more decompositions exist.
