Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131310, here are decompositions:

7 + 131303 = 131310
13 + 131297 = 131310
17 + 131293 = 131310
43 + 131267 = 131310
59 + 131251 = 131310
61 + 131249 = 131310
79 + 131231 = 131310
89 + 131221 = 131310

Showing the first eight; more decompositions exist.
