Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13330, here are decompositions:
- 3 + 13327 = 13330
- 17 + 13313 = 13330
- 71 + 13259 = 13330
- 89 + 13241 = 13330
- 101 + 13229 = 13330
- 113 + 13217 = 13330
- 167 + 13163 = 13330
- 179 + 13151 = 13330
Showing the first eight; more decompositions exist.
