Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597852, here are decompositions:

29 + 31597823 = 31597852
59 + 31597793 = 31597852
89 + 31597763 = 31597852
113 + 31597739 = 31597852
131 + 31597721 = 31597852
179 + 31597673 = 31597852
239 + 31597613 = 31597852
281 + 31597571 = 31597852

Showing the first eight; more decompositions exist.
