Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42858, here are decompositions:
- 5 + 42853 = 42858
- 17 + 42841 = 42858
- 19 + 42839 = 42858
- 29 + 42829 = 42858
- 37 + 42821 = 42858
- 61 + 42797 = 42858
- 71 + 42787 = 42858
- 107 + 42751 = 42858
Showing the first eight; more decompositions exist.
