Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7678, here are decompositions:
- 5 + 7673 = 7678
- 29 + 7649 = 7678
- 71 + 7607 = 7678
- 89 + 7589 = 7678
- 101 + 7577 = 7678
- 131 + 7547 = 7678
- 137 + 7541 = 7678
- 149 + 7529 = 7678
Showing the first eight; more decompositions exist.
