Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13388, here are decompositions:
- 7 + 13381 = 13388
- 61 + 13327 = 13388
- 79 + 13309 = 13388
- 97 + 13291 = 13388
- 139 + 13249 = 13388
- 211 + 13177 = 13388
- 229 + 13159 = 13388
- 241 + 13147 = 13388
Showing the first eight; more decompositions exist.
