Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12706, here are decompositions:

3 + 12703 = 12706
17 + 12689 = 12706
47 + 12659 = 12706
53 + 12653 = 12706
59 + 12647 = 12706
137 + 12569 = 12706
167 + 12539 = 12706
179 + 12527 = 12706

Showing the first eight; more decompositions exist.
