Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9100, here are decompositions:
- 41 + 9059 = 9100
- 59 + 9041 = 9100
- 71 + 9029 = 9100
- 89 + 9011 = 9100
- 101 + 8999 = 9100
- 131 + 8969 = 9100
- 137 + 8963 = 9100
- 149 + 8951 = 9100
Showing the first eight; more decompositions exist.
