Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12426, here are decompositions:

5 + 12421 = 12426
13 + 12413 = 12426
17 + 12409 = 12426
47 + 12379 = 12426
53 + 12373 = 12426
79 + 12347 = 12426
83 + 12343 = 12426
97 + 12329 = 12426

Showing the first eight; more decompositions exist.
