Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597496, here are decompositions:

3 + 31597493 = 31597496
13 + 31597483 = 31597496
43 + 31597453 = 31597496
79 + 31597417 = 31597496
283 + 31597213 = 31597496
367 + 31597129 = 31597496
397 + 31597099 = 31597496
499 + 31596997 = 31597496

Showing the first eight; more decompositions exist.
