Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18316, here are decompositions:
- 3 + 18313 = 18316
- 5 + 18311 = 18316
- 29 + 18287 = 18316
- 47 + 18269 = 18316
- 59 + 18257 = 18316
- 83 + 18233 = 18316
- 167 + 18149 = 18316
- 173 + 18143 = 18316
Showing the first eight; more decompositions exist.
