Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597052, here are decompositions:

61 + 31596991 = 31597052
103 + 31596949 = 31597052
139 + 31596913 = 31597052
163 + 31596889 = 31597052
283 + 31596769 = 31597052
373 + 31596679 = 31597052
379 + 31596673 = 31597052
439 + 31596613 = 31597052

Showing the first eight; more decompositions exist.
