Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91998, here are decompositions:
- 29 + 91969 = 91998
- 31 + 91967 = 91998
- 37 + 91961 = 91998
- 41 + 91957 = 91998
- 47 + 91951 = 91998
- 59 + 91939 = 91998
- 89 + 91909 = 91998
- 131 + 91867 = 91998
Showing the first eight; more decompositions exist.
