Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81082, here are decompositions:

5 + 81077 = 81082
11 + 81071 = 81082
41 + 81041 = 81082
59 + 81023 = 81082
149 + 80933 = 81082
173 + 80909 = 81082
233 + 80849 = 81082
251 + 80831 = 81082

Showing the first eight; more decompositions exist.
