Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42748, here are decompositions:
- 5 + 42743 = 42748
- 11 + 42737 = 42748
- 29 + 42719 = 42748
- 47 + 42701 = 42748
- 59 + 42689 = 42748
- 71 + 42677 = 42748
- 107 + 42641 = 42748
- 137 + 42611 = 42748
Showing the first eight; more decompositions exist.
