Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12544, here are decompositions:

3 + 12541 = 12544
5 + 12539 = 12544
17 + 12527 = 12544
41 + 12503 = 12544
47 + 12497 = 12544
53 + 12491 = 12544
71 + 12473 = 12544
107 + 12437 = 12544

Showing the first eight; more decompositions exist.
