Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13512, here are decompositions:
- 13 + 13499 = 13512
- 43 + 13469 = 13512
- 61 + 13451 = 13512
- 71 + 13441 = 13512
- 101 + 13411 = 13512
- 113 + 13399 = 13512
- 131 + 13381 = 13512
- 173 + 13339 = 13512
Showing the first eight; more decompositions exist.
