Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597292, here are decompositions:

31 + 31597261 = 31597292
61 + 31597231 = 31597292
79 + 31597213 = 31597292
163 + 31597129 = 31597292
193 + 31597099 = 31597292
211 + 31597081 = 31597292
241 + 31597051 = 31597292
379 + 31596913 = 31597292

Showing the first eight; more decompositions exist.
