Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597474, here are decompositions:

3 + 31597471 = 31597474
107 + 31597367 = 31597474
137 + 31597337 = 31597474
191 + 31597283 = 31597474
347 + 31597127 = 31597474
353 + 31597121 = 31597474
431 + 31597043 = 31597474
443 + 31597031 = 31597474

Showing the first eight; more decompositions exist.
