Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13080, here are decompositions:

17 + 13063 = 13080
31 + 13049 = 13080
37 + 13043 = 13080
43 + 13037 = 13080
47 + 13033 = 13080
71 + 13009 = 13080
73 + 13007 = 13080
79 + 13001 = 13080

Showing the first eight; more decompositions exist.
