Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12408, here are decompositions:

7 + 12401 = 12408
17 + 12391 = 12408
29 + 12379 = 12408
31 + 12377 = 12408
61 + 12347 = 12408
79 + 12329 = 12408
107 + 12301 = 12408
127 + 12281 = 12408

Showing the first eight; more decompositions exist.
