Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597422, here are decompositions:

5 + 31597417 = 31597422
11 + 31597411 = 31597422
139 + 31597283 = 31597422
179 + 31597243 = 31597422
191 + 31597231 = 31597422
223 + 31597199 = 31597422
271 + 31597151 = 31597422
293 + 31597129 = 31597422

Showing the first eight; more decompositions exist.
