Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135252, here are decompositions:
- 11 + 135241 = 135252
- 31 + 135221 = 135252
- 41 + 135211 = 135252
- 43 + 135209 = 135252
- 59 + 135193 = 135252
- 71 + 135181 = 135252
- 79 + 135173 = 135252
- 101 + 135151 = 135252
Showing the first eight; more decompositions exist.
