Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12546, here are decompositions:

5 + 12541 = 12546
7 + 12539 = 12546
19 + 12527 = 12546
29 + 12517 = 12546
43 + 12503 = 12546
59 + 12487 = 12546
67 + 12479 = 12546
73 + 12473 = 12546

Showing the first eight; more decompositions exist.
