Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81460, here are decompositions:

3 + 81457 = 81460
59 + 81401 = 81460
89 + 81371 = 81460
101 + 81359 = 81460
107 + 81353 = 81460
167 + 81293 = 81460
179 + 81281 = 81460
227 + 81233 = 81460

Showing the first eight; more decompositions exist.
