Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597246, here are decompositions:

3 + 31597243 = 31597246
47 + 31597199 = 31597246
269 + 31596977 = 31597246
347 + 31596899 = 31597246
389 + 31596857 = 31597246
449 + 31596797 = 31597246
503 + 31596743 = 31597246
773 + 31596473 = 31597246

Showing the first eight; more decompositions exist.
