Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135238, here are decompositions:
- 17 + 135221 = 135238
- 29 + 135209 = 135238
- 41 + 135197 = 135238
- 107 + 135131 = 135238
- 137 + 135101 = 135238
- 149 + 135089 = 135238
- 179 + 135059 = 135238
- 239 + 134999 = 135238
Showing the first eight; more decompositions exist.
