Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81456, here are decompositions:

17 + 81439 = 81456
47 + 81409 = 81456
83 + 81373 = 81456
97 + 81359 = 81456
103 + 81353 = 81456
107 + 81349 = 81456
113 + 81343 = 81456
149 + 81307 = 81456

Showing the first eight; more decompositions exist.
