Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67870, here are decompositions:
- 3 + 67867 = 67870
- 17 + 67853 = 67870
- 41 + 67829 = 67870
- 107 + 67763 = 67870
- 113 + 67757 = 67870
- 137 + 67733 = 67870
- 191 + 67679 = 67870
- 239 + 67631 = 67870
Showing the first eight; more decompositions exist.
