Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12600, here are decompositions:

11 + 12589 = 12600
17 + 12583 = 12600
23 + 12577 = 12600
31 + 12569 = 12600
47 + 12553 = 12600
53 + 12547 = 12600
59 + 12541 = 12600
61 + 12539 = 12600

Showing the first eight; more decompositions exist.
