Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9112, here are decompositions:
- 3 + 9109 = 9112
- 53 + 9059 = 9112
- 71 + 9041 = 9112
- 83 + 9029 = 9112
- 101 + 9011 = 9112
- 113 + 8999 = 9112
- 149 + 8963 = 9112
- 179 + 8933 = 9112
Showing the first eight; more decompositions exist.
