Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13446, here are decompositions:

5 + 13441 = 13446
29 + 13417 = 13446
47 + 13399 = 13446
79 + 13367 = 13446
107 + 13339 = 13446
109 + 13337 = 13446
137 + 13309 = 13446
149 + 13297 = 13446

Showing the first eight; more decompositions exist.
