Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13260, here are decompositions:
- 11 + 13249 = 13260
- 19 + 13241 = 13260
- 31 + 13229 = 13260
- 41 + 13219 = 13260
- 43 + 13217 = 13260
- 73 + 13187 = 13260
- 83 + 13177 = 13260
- 89 + 13171 = 13260
Showing the first eight; more decompositions exist.
