Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86342, here are decompositions:

19 + 86323 = 86342
31 + 86311 = 86342
73 + 86269 = 86342
79 + 86263 = 86342
103 + 86239 = 86342
163 + 86179 = 86342
181 + 86161 = 86342
199 + 86143 = 86342

Showing the first eight; more decompositions exist.
