Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597344, here are decompositions:

7 + 31597337 = 31597344
61 + 31597283 = 31597344
83 + 31597261 = 31597344
101 + 31597243 = 31597344
113 + 31597231 = 31597344
131 + 31597213 = 31597344
167 + 31597177 = 31597344
193 + 31597151 = 31597344

Showing the first eight; more decompositions exist.
