Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7684, here are decompositions:
- 3 + 7681 = 7684
- 11 + 7673 = 7684
- 41 + 7643 = 7684
- 101 + 7583 = 7684
- 107 + 7577 = 7684
- 137 + 7547 = 7684
- 167 + 7517 = 7684
- 197 + 7487 = 7684
Showing the first eight; more decompositions exist.
