Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17712, here are decompositions:
- 5 + 17707 = 17712
- 29 + 17683 = 17712
- 31 + 17681 = 17712
- 43 + 17669 = 17712
- 53 + 17659 = 17712
- 89 + 17623 = 17712
- 103 + 17609 = 17712
- 113 + 17599 = 17712
Showing the first eight; more decompositions exist.
