Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131534, here are decompositions:

37 + 131497 = 131534
97 + 131437 = 131534
103 + 131431 = 131534
163 + 131371 = 131534
223 + 131311 = 131534
241 + 131293 = 131534
283 + 131251 = 131534
313 + 131221 = 131534

Showing the first eight; more decompositions exist.
