Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135838, here are decompositions:
- 107 + 135731 = 135838
- 137 + 135701 = 135838
- 167 + 135671 = 135838
- 191 + 135647 = 135838
- 239 + 135599 = 135838
- 257 + 135581 = 135838
- 359 + 135479 = 135838
- 389 + 135449 = 135838
Showing the first eight; more decompositions exist.
