Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91120, here are decompositions:
- 23 + 91097 = 91120
- 41 + 91079 = 91120
- 101 + 91019 = 91120
- 131 + 90989 = 91120
- 149 + 90971 = 91120
- 173 + 90947 = 91120
- 233 + 90887 = 91120
- 257 + 90863 = 91120
Showing the first eight; more decompositions exist.
