Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13248, here are decompositions:
- 7 + 13241 = 13248
- 19 + 13229 = 13248
- 29 + 13219 = 13248
- 31 + 13217 = 13248
- 61 + 13187 = 13248
- 71 + 13177 = 13248
- 89 + 13159 = 13248
- 97 + 13151 = 13248
Showing the first eight; more decompositions exist.
