Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12738, here are decompositions:

17 + 12721 = 12738
41 + 12697 = 12738
67 + 12671 = 12738
79 + 12659 = 12738
97 + 12641 = 12738
101 + 12637 = 12738
127 + 12611 = 12738
137 + 12601 = 12738

Showing the first eight; more decompositions exist.
