Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91216, here are decompositions:
- 17 + 91199 = 91216
- 23 + 91193 = 91216
- 53 + 91163 = 91216
- 89 + 91127 = 91216
- 137 + 91079 = 91216
- 197 + 91019 = 91216
- 227 + 90989 = 91216
- 239 + 90977 = 91216
Showing the first eight; more decompositions exist.
