Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33870, here are decompositions:
- 7 + 33863 = 33870
- 13 + 33857 = 33870
- 19 + 33851 = 33870
- 41 + 33829 = 33870
- 43 + 33827 = 33870
- 59 + 33811 = 33870
- 61 + 33809 = 33870
- 73 + 33797 = 33870
Showing the first eight; more decompositions exist.
