Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91288, here are decompositions:
- 5 + 91283 = 91288
- 59 + 91229 = 91288
- 89 + 91199 = 91288
- 137 + 91151 = 91288
- 149 + 91139 = 91288
- 167 + 91121 = 91288
- 191 + 91097 = 91288
- 269 + 91019 = 91288
Showing the first eight; more decompositions exist.
