Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67906, here are decompositions:
- 5 + 67901 = 67906
- 23 + 67883 = 67906
- 53 + 67853 = 67906
- 149 + 67757 = 67906
- 173 + 67733 = 67906
- 197 + 67709 = 67906
- 227 + 67679 = 67906
- 317 + 67589 = 67906
Showing the first eight; more decompositions exist.
