Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12620, here are decompositions:

7 + 12613 = 12620
19 + 12601 = 12620
31 + 12589 = 12620
37 + 12583 = 12620
43 + 12577 = 12620
67 + 12553 = 12620
73 + 12547 = 12620
79 + 12541 = 12620

Showing the first eight; more decompositions exist.
