Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131342, here are decompositions:

31 + 131311 = 131342
139 + 131203 = 131342
193 + 131149 = 131342
199 + 131143 = 131342
229 + 131113 = 131342
241 + 131101 = 131342
271 + 131071 = 131342
283 + 131059 = 131342

Showing the first eight; more decompositions exist.
