Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597448, here are decompositions:

31 + 31597417 = 31597448
37 + 31597411 = 31597448
271 + 31597177 = 31597448
349 + 31597099 = 31597448
367 + 31597081 = 31597448
397 + 31597051 = 31597448
457 + 31596991 = 31597448
499 + 31596949 = 31597448

Showing the first eight; more decompositions exist.
