Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597522, here are decompositions:

29 + 31597493 = 31597522
239 + 31597283 = 31597522
269 + 31597253 = 31597522
401 + 31597121 = 31597522
479 + 31597043 = 31597522
491 + 31597031 = 31597522
599 + 31596923 = 31597522
641 + 31596881 = 31597522

Showing the first eight; more decompositions exist.
