Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597148, here are decompositions:

19 + 31597129 = 31597148
67 + 31597081 = 31597148
97 + 31597051 = 31597148
151 + 31596997 = 31597148
157 + 31596991 = 31597148
199 + 31596949 = 31597148
241 + 31596907 = 31597148
379 + 31596769 = 31597148

Showing the first eight; more decompositions exist.
