Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81412, here are decompositions:

3 + 81409 = 81412
11 + 81401 = 81412
41 + 81371 = 81412
53 + 81359 = 81412
59 + 81353 = 81412
113 + 81299 = 81412
131 + 81281 = 81412
173 + 81239 = 81412

Showing the first eight; more decompositions exist.
