Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131346, here are decompositions:

29 + 131317 = 131346
43 + 131303 = 131346
53 + 131293 = 131346
79 + 131267 = 131346
97 + 131249 = 131346
197 + 131149 = 131346
233 + 131113 = 131346
283 + 131063 = 131346

Showing the first eight; more decompositions exist.
