Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597410, here are decompositions:

43 + 31597367 = 31597410
73 + 31597337 = 31597410
127 + 31597283 = 31597410
149 + 31597261 = 31597410
157 + 31597253 = 31597410
167 + 31597243 = 31597410
179 + 31597231 = 31597410
197 + 31597213 = 31597410

Showing the first eight; more decompositions exist.
