Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13392, here are decompositions:
- 11 + 13381 = 13392
- 53 + 13339 = 13392
- 61 + 13331 = 13392
- 79 + 13313 = 13392
- 83 + 13309 = 13392
- 101 + 13291 = 13392
- 151 + 13241 = 13392
- 163 + 13229 = 13392
Showing the first eight; more decompositions exist.
