Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12570, here are decompositions:

17 + 12553 = 12570
23 + 12547 = 12570
29 + 12541 = 12570
31 + 12539 = 12570
43 + 12527 = 12570
53 + 12517 = 12570
59 + 12511 = 12570
67 + 12503 = 12570

Showing the first eight; more decompositions exist.
