Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12670, here are decompositions:

11 + 12659 = 12670
17 + 12653 = 12670
23 + 12647 = 12670
29 + 12641 = 12670
59 + 12611 = 12670
101 + 12569 = 12670
131 + 12539 = 12670
167 + 12503 = 12670

Showing the first eight; more decompositions exist.
