Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597504, here are decompositions:

11 + 31597493 = 31597504
137 + 31597367 = 31597504
167 + 31597337 = 31597504
251 + 31597253 = 31597504
353 + 31597151 = 31597504
383 + 31597121 = 31597504
461 + 31597043 = 31597504
647 + 31596857 = 31597504

Showing the first eight; more decompositions exist.
