Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13420, here are decompositions:
- 3 + 13417 = 13420
- 23 + 13397 = 13420
- 53 + 13367 = 13420
- 83 + 13337 = 13420
- 89 + 13331 = 13420
- 107 + 13313 = 13420
- 179 + 13241 = 13420
- 191 + 13229 = 13420
Showing the first eight; more decompositions exist.
