Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13458, here are decompositions:

7 + 13451 = 13458
17 + 13441 = 13458
37 + 13421 = 13458
41 + 13417 = 13458
47 + 13411 = 13458
59 + 13399 = 13458
61 + 13397 = 13458
127 + 13331 = 13458

Showing the first eight; more decompositions exist.
