Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597254, here are decompositions:

11 + 31597243 = 31597254
23 + 31597231 = 31597254
41 + 31597213 = 31597254
103 + 31597151 = 31597254
127 + 31597127 = 31597254
173 + 31597081 = 31597254
211 + 31597043 = 31597254
223 + 31597031 = 31597254

Showing the first eight; more decompositions exist.
