Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597260, here are decompositions:

7 + 31597253 = 31597260
17 + 31597243 = 31597260
29 + 31597231 = 31597260
47 + 31597213 = 31597260
61 + 31597199 = 31597260
83 + 31597177 = 31597260
109 + 31597151 = 31597260
131 + 31597129 = 31597260

Showing the first eight; more decompositions exist.
