Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597326, here are decompositions:

43 + 31597283 = 31597326
73 + 31597253 = 31597326
83 + 31597243 = 31597326
113 + 31597213 = 31597326
127 + 31597199 = 31597326
149 + 31597177 = 31597326
197 + 31597129 = 31597326
199 + 31597127 = 31597326

Showing the first eight; more decompositions exist.
