Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12648, here are decompositions:

7 + 12641 = 12648
11 + 12637 = 12648
29 + 12619 = 12648
37 + 12611 = 12648
47 + 12601 = 12648
59 + 12589 = 12648
71 + 12577 = 12648
79 + 12569 = 12648

Showing the first eight; more decompositions exist.
