Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7798, here are decompositions:
- 5 + 7793 = 7798
- 41 + 7757 = 7798
- 71 + 7727 = 7798
- 107 + 7691 = 7798
- 149 + 7649 = 7798
- 191 + 7607 = 7798
- 239 + 7559 = 7798
- 251 + 7547 = 7798
Showing the first eight; more decompositions exist.
