Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597874, here are decompositions:

31 + 31597843 = 31597874
73 + 31597801 = 31597874
97 + 31597777 = 31597874
157 + 31597717 = 31597874
181 + 31597693 = 31597874
223 + 31597651 = 31597874
271 + 31597603 = 31597874
367 + 31597507 = 31597874

Showing the first eight; more decompositions exist.
