Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135742, here are decompositions:
- 11 + 135731 = 135742
- 23 + 135719 = 135742
- 41 + 135701 = 135742
- 71 + 135671 = 135742
- 149 + 135593 = 135742
- 263 + 135479 = 135742
- 281 + 135461 = 135742
- 293 + 135449 = 135742
Showing the first eight; more decompositions exist.
