Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597244, here are decompositions:

13 + 31597231 = 31597244
31 + 31597213 = 31597244
67 + 31597177 = 31597244
163 + 31597081 = 31597244
193 + 31597051 = 31597244
241 + 31597003 = 31597244
331 + 31596913 = 31597244
337 + 31596907 = 31597244

Showing the first eight; more decompositions exist.
