Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13508, here are decompositions:
- 31 + 13477 = 13508
- 67 + 13441 = 13508
- 97 + 13411 = 13508
- 109 + 13399 = 13508
- 127 + 13381 = 13508
- 181 + 13327 = 13508
- 199 + 13309 = 13508
- 211 + 13297 = 13508
Showing the first eight; more decompositions exist.
