Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597300, here are decompositions:

17 + 31597283 = 31597300
47 + 31597253 = 31597300
101 + 31597199 = 31597300
149 + 31597151 = 31597300
173 + 31597127 = 31597300
179 + 31597121 = 31597300
257 + 31597043 = 31597300
269 + 31597031 = 31597300

Showing the first eight; more decompositions exist.
