Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597224, here are decompositions:

11 + 31597213 = 31597224
47 + 31597177 = 31597224
73 + 31597151 = 31597224
97 + 31597127 = 31597224
103 + 31597121 = 31597224
173 + 31597051 = 31597224
181 + 31597043 = 31597224
193 + 31597031 = 31597224

Showing the first eight; more decompositions exist.
