Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81334, here are decompositions:

3 + 81331 = 81334
41 + 81293 = 81334
53 + 81281 = 81334
101 + 81233 = 81334
131 + 81203 = 81334
137 + 81197 = 81334
233 + 81101 = 81334
251 + 81083 = 81334

Showing the first eight; more decompositions exist.
