Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81336, here are decompositions:

5 + 81331 = 81336
29 + 81307 = 81336
37 + 81299 = 81336
43 + 81293 = 81336
53 + 81283 = 81336
97 + 81239 = 81336
103 + 81233 = 81336
113 + 81223 = 81336

Showing the first eight; more decompositions exist.
