Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87726, here are decompositions:
- 5 + 87721 = 87726
- 7 + 87719 = 87726
- 29 + 87697 = 87726
- 43 + 87683 = 87726
- 47 + 87679 = 87726
- 83 + 87643 = 87726
- 97 + 87629 = 87726
- 103 + 87623 = 87726
Showing the first eight; more decompositions exist.
