Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597104, here are decompositions:

5 + 31597099 = 31597104
23 + 31597081 = 31597104
53 + 31597051 = 31597104
61 + 31597043 = 31597104
73 + 31597031 = 31597104
101 + 31597003 = 31597104
107 + 31596997 = 31597104
113 + 31596991 = 31597104

Showing the first eight; more decompositions exist.
