Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712, here are decompositions:
- 5 + 8707 = 8712
- 13 + 8699 = 8712
- 19 + 8693 = 8712
- 23 + 8689 = 8712
- 31 + 8681 = 8712
- 43 + 8669 = 8712
- 71 + 8641 = 8712
- 83 + 8629 = 8712
Showing the first eight; more decompositions exist.
