Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13318, here are decompositions:
- 5 + 13313 = 13318
- 59 + 13259 = 13318
- 89 + 13229 = 13318
- 101 + 13217 = 13318
- 131 + 13187 = 13318
- 167 + 13151 = 13318
- 191 + 13127 = 13318
- 197 + 13121 = 13318
Showing the first eight; more decompositions exist.
