Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17688, here are decompositions:
- 5 + 17683 = 17688
- 7 + 17681 = 17688
- 19 + 17669 = 17688
- 29 + 17659 = 17688
- 31 + 17657 = 17688
- 61 + 17627 = 17688
- 79 + 17609 = 17688
- 89 + 17599 = 17688
Showing the first eight; more decompositions exist.
