Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81348, here are decompositions:

5 + 81343 = 81348
17 + 81331 = 81348
41 + 81307 = 81348
67 + 81281 = 81348
109 + 81239 = 81348
149 + 81199 = 81348
151 + 81197 = 81348
167 + 81181 = 81348

Showing the first eight; more decompositions exist.
