Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15316, here are decompositions:
- 3 + 15313 = 15316
- 17 + 15299 = 15316
- 29 + 15287 = 15316
- 47 + 15269 = 15316
- 53 + 15263 = 15316
- 83 + 15233 = 15316
- 89 + 15227 = 15316
- 167 + 15149 = 15316
Showing the first eight; more decompositions exist.
