Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13406, here are decompositions:
- 7 + 13399 = 13406
- 67 + 13339 = 13406
- 79 + 13327 = 13406
- 97 + 13309 = 13406
- 109 + 13297 = 13406
- 139 + 13267 = 13406
- 157 + 13249 = 13406
- 223 + 13183 = 13406
Showing the first eight; more decompositions exist.
