Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131676, here are decompositions:

5 + 131671 = 131676
37 + 131639 = 131676
59 + 131617 = 131676
157 + 131519 = 131676
179 + 131497 = 131676
197 + 131479 = 131676
199 + 131477 = 131676
227 + 131449 = 131676

Showing the first eight; more decompositions exist.
