Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13582, here are decompositions:
- 5 + 13577 = 13582
- 29 + 13553 = 13582
- 59 + 13523 = 13582
- 83 + 13499 = 13582
- 113 + 13469 = 13582
- 131 + 13451 = 13582
- 251 + 13331 = 13582
- 269 + 13313 = 13582
Showing the first eight; more decompositions exist.
