Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81094, here are decompositions:

11 + 81083 = 81094
17 + 81077 = 81094
23 + 81071 = 81094
47 + 81047 = 81094
53 + 81041 = 81094
71 + 81023 = 81094
131 + 80963 = 81094
197 + 80897 = 81094

Showing the first eight; more decompositions exist.
