Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597152, here are decompositions:

23 + 31597129 = 31597152
31 + 31597121 = 31597152
53 + 31597099 = 31597152
71 + 31597081 = 31597152
101 + 31597051 = 31597152
109 + 31597043 = 31597152
149 + 31597003 = 31597152
229 + 31596923 = 31597152

Showing the first eight; more decompositions exist.
