Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42856, here are decompositions:
- 3 + 42853 = 42856
- 17 + 42839 = 42856
- 59 + 42797 = 42856
- 83 + 42773 = 42856
- 89 + 42767 = 42856
- 113 + 42743 = 42856
- 137 + 42719 = 42856
- 167 + 42689 = 42856
Showing the first eight; more decompositions exist.
