Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12642, here are decompositions:

5 + 12637 = 12642
23 + 12619 = 12642
29 + 12613 = 12642
31 + 12611 = 12642
41 + 12601 = 12642
53 + 12589 = 12642
59 + 12583 = 12642
73 + 12569 = 12642

Showing the first eight; more decompositions exist.
