Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597358, here are decompositions:

97 + 31597261 = 31597358
127 + 31597231 = 31597358
181 + 31597177 = 31597358
229 + 31597129 = 31597358
277 + 31597081 = 31597358
307 + 31597051 = 31597358
367 + 31596991 = 31597358
409 + 31596949 = 31597358

Showing the first eight; more decompositions exist.
