Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135904, here are decompositions:
- 5 + 135899 = 135904
- 11 + 135893 = 135904
- 17 + 135887 = 135904
- 53 + 135851 = 135904
- 173 + 135731 = 135904
- 233 + 135671 = 135904
- 257 + 135647 = 135904
- 281 + 135623 = 135904
Showing the first eight; more decompositions exist.
