Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9240, here are decompositions:
- 13 + 9227 = 9240
- 19 + 9221 = 9240
- 31 + 9209 = 9240
- 37 + 9203 = 9240
- 41 + 9199 = 9240
- 53 + 9187 = 9240
- 59 + 9181 = 9240
- 67 + 9173 = 9240
Showing the first eight; more decompositions exist.
