Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81352, here are decompositions:

3 + 81349 = 81352
53 + 81299 = 81352
59 + 81293 = 81352
71 + 81281 = 81352
113 + 81239 = 81352
149 + 81203 = 81352
179 + 81173 = 81352
233 + 81119 = 81352

Showing the first eight; more decompositions exist.
