Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13598, here are decompositions:
- 7 + 13591 = 13598
- 31 + 13567 = 13598
- 61 + 13537 = 13598
- 157 + 13441 = 13598
- 181 + 13417 = 13598
- 199 + 13399 = 13598
- 271 + 13327 = 13598
- 307 + 13291 = 13598
Showing the first eight; more decompositions exist.
