Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81704, here are decompositions:

3 + 81701 = 81704
37 + 81667 = 81704
67 + 81637 = 81704
151 + 81553 = 81704
157 + 81547 = 81704
241 + 81463 = 81704
283 + 81421 = 81704
331 + 81373 = 81704

Showing the first eight; more decompositions exist.
