Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13452, here are decompositions:
- 11 + 13441 = 13452
- 31 + 13421 = 13452
- 41 + 13411 = 13452
- 53 + 13399 = 13452
- 71 + 13381 = 13452
- 113 + 13339 = 13452
- 139 + 13313 = 13452
- 193 + 13259 = 13452
Showing the first eight; more decompositions exist.
