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.
