Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135258, here are decompositions:
- 17 + 135241 = 135258
- 37 + 135221 = 135258
- 47 + 135211 = 135258
- 61 + 135197 = 135258
- 107 + 135151 = 135258
- 127 + 135131 = 135258
- 139 + 135119 = 135258
- 157 + 135101 = 135258
Showing the first eight; more decompositions exist.
