Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597094, here are decompositions:

13 + 31597081 = 31597094
43 + 31597051 = 31597094
97 + 31596997 = 31597094
103 + 31596991 = 31597094
181 + 31596913 = 31597094
211 + 31596883 = 31597094
337 + 31596757 = 31597094
421 + 31596673 = 31597094

Showing the first eight; more decompositions exist.
