Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89668, here are decompositions:
- 11 + 89657 = 89668
- 41 + 89627 = 89668
- 71 + 89597 = 89668
- 101 + 89567 = 89668
- 107 + 89561 = 89668
- 149 + 89519 = 89668
- 167 + 89501 = 89668
- 191 + 89477 = 89668
Showing the first eight; more decompositions exist.
