Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81076, here are decompositions:

5 + 81071 = 81076
29 + 81047 = 81076
53 + 81023 = 81076
59 + 81017 = 81076
113 + 80963 = 81076
167 + 80909 = 81076
179 + 80897 = 81076
227 + 80849 = 81076

Showing the first eight; more decompositions exist.
