Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28318, here are decompositions:
- 11 + 28307 = 28318
- 29 + 28289 = 28318
- 41 + 28277 = 28318
- 89 + 28229 = 28318
- 107 + 28211 = 28318
- 137 + 28181 = 28318
- 167 + 28151 = 28318
- 317 + 28001 = 28318
Showing the first eight; more decompositions exist.
