Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131354, here are decompositions:

37 + 131317 = 131354
43 + 131311 = 131354
61 + 131293 = 131354
103 + 131251 = 131354
151 + 131203 = 131354
211 + 131143 = 131354
241 + 131113 = 131354
283 + 131071 = 131354

Showing the first eight; more decompositions exist.
