Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11558, here are decompositions:
- 7 + 11551 = 11558
- 31 + 11527 = 11558
- 61 + 11497 = 11558
- 67 + 11491 = 11558
- 229 + 11329 = 11558
- 241 + 11317 = 11558
- 271 + 11287 = 11558
- 307 + 11251 = 11558
Showing the first eight; more decompositions exist.
