Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7724, here are decompositions:
- 7 + 7717 = 7724
- 37 + 7687 = 7724
- 43 + 7681 = 7724
- 103 + 7621 = 7724
- 151 + 7573 = 7724
- 163 + 7561 = 7724
- 307 + 7417 = 7724
- 313 + 7411 = 7724
Showing the first eight; more decompositions exist.
