Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7804, here are decompositions:
- 11 + 7793 = 7804
- 47 + 7757 = 7804
- 101 + 7703 = 7804
- 113 + 7691 = 7804
- 131 + 7673 = 7804
- 197 + 7607 = 7804
- 227 + 7577 = 7804
- 257 + 7547 = 7804
Showing the first eight; more decompositions exist.
