Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91122, here are decompositions:
- 23 + 91099 = 91122
- 41 + 91081 = 91122
- 43 + 91079 = 91122
- 89 + 91033 = 91122
- 103 + 91019 = 91122
- 113 + 91009 = 91122
- 151 + 90971 = 91122
- 191 + 90931 = 91122
Showing the first eight; more decompositions exist.
