Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597424, here are decompositions:

7 + 31597417 = 31597424
13 + 31597411 = 31597424
163 + 31597261 = 31597424
181 + 31597243 = 31597424
193 + 31597231 = 31597424
211 + 31597213 = 31597424
373 + 31597051 = 31597424
421 + 31597003 = 31597424

Showing the first eight; more decompositions exist.
