Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13258, here are decompositions:
- 17 + 13241 = 13258
- 29 + 13229 = 13258
- 41 + 13217 = 13258
- 71 + 13187 = 13258
- 107 + 13151 = 13258
- 131 + 13127 = 13258
- 137 + 13121 = 13258
- 149 + 13109 = 13258
Showing the first eight; more decompositions exist.
