Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131260, here are decompositions:

11 + 131249 = 131260
29 + 131231 = 131260
47 + 131213 = 131260
89 + 131171 = 131260
131 + 131129 = 131260
149 + 131111 = 131260
197 + 131063 = 131260
251 + 131009 = 131260

Showing the first eight; more decompositions exist.
