Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7704, here are decompositions:
- 5 + 7699 = 7704
- 13 + 7691 = 7704
- 17 + 7687 = 7704
- 23 + 7681 = 7704
- 31 + 7673 = 7704
- 61 + 7643 = 7704
- 83 + 7621 = 7704
- 97 + 7607 = 7704
Showing the first eight; more decompositions exist.
