Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18460, here are decompositions:

3 + 18457 = 18460
17 + 18443 = 18460
47 + 18413 = 18460
59 + 18401 = 18460
89 + 18371 = 18460
107 + 18353 = 18460
131 + 18329 = 18460
149 + 18311 = 18460

Showing the first eight; more decompositions exist.
