Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153742, here are decompositions:
- 3 + 153739 = 153742
- 23 + 153719 = 153742
- 41 + 153701 = 153742
- 53 + 153689 = 153742
- 101 + 153641 = 153742
- 131 + 153611 = 153742
- 179 + 153563 = 153742
- 233 + 153509 = 153742
Showing the first eight; more decompositions exist.
