Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7708, here are decompositions:
- 5 + 7703 = 7708
- 17 + 7691 = 7708
- 59 + 7649 = 7708
- 101 + 7607 = 7708
- 131 + 7577 = 7708
- 149 + 7559 = 7708
- 167 + 7541 = 7708
- 179 + 7529 = 7708
Showing the first eight; more decompositions exist.
