Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76840, here are decompositions:
- 3 + 76837 = 76840
- 11 + 76829 = 76840
- 59 + 76781 = 76840
- 83 + 76757 = 76840
- 107 + 76733 = 76840
- 167 + 76673 = 76840
- 173 + 76667 = 76840
- 191 + 76649 = 76840
Showing the first eight; more decompositions exist.
