Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159742, here are decompositions:
- 3 + 159739 = 159742
- 5 + 159737 = 159742
- 41 + 159701 = 159742
- 59 + 159683 = 159742
- 71 + 159671 = 159742
- 113 + 159629 = 159742
- 173 + 159569 = 159742
- 179 + 159563 = 159742
Showing the first eight; more decompositions exist.
