Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31260, here are decompositions:

7 + 31253 = 31260
11 + 31249 = 31260
13 + 31247 = 31260
23 + 31237 = 31260
29 + 31231 = 31260
37 + 31223 = 31260
41 + 31219 = 31260
67 + 31193 = 31260

Showing the first eight; more decompositions exist.
