Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597092, here are decompositions:

11 + 31597081 = 31597092
41 + 31597051 = 31597092
61 + 31597031 = 31597092
89 + 31597003 = 31597092
101 + 31596991 = 31597092
179 + 31596913 = 31597092
193 + 31596899 = 31597092
211 + 31596881 = 31597092

Showing the first eight; more decompositions exist.
