Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9216, here are decompositions:
- 7 + 9209 = 9216
- 13 + 9203 = 9216
- 17 + 9199 = 9216
- 29 + 9187 = 9216
- 43 + 9173 = 9216
- 59 + 9157 = 9216
- 79 + 9137 = 9216
- 83 + 9133 = 9216
Showing the first eight; more decompositions exist.
