Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597534, here are decompositions:

41 + 31597493 = 31597534
167 + 31597367 = 31597534
197 + 31597337 = 31597534
251 + 31597283 = 31597534
281 + 31597253 = 31597534
383 + 31597151 = 31597534
491 + 31597043 = 31597534
503 + 31597031 = 31597534

Showing the first eight; more decompositions exist.
