Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9118, here are decompositions:
- 59 + 9059 = 9118
- 89 + 9029 = 9118
- 107 + 9011 = 9118
- 149 + 8969 = 9118
- 167 + 8951 = 9118
- 251 + 8867 = 9118
- 257 + 8861 = 9118
- 269 + 8849 = 9118
Showing the first eight; more decompositions exist.
