Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16418, here are decompositions:
- 7 + 16411 = 16418
- 37 + 16381 = 16418
- 79 + 16339 = 16418
- 151 + 16267 = 16418
- 229 + 16189 = 16418
- 277 + 16141 = 16418
- 307 + 16111 = 16418
- 331 + 16087 = 16418
Showing the first eight; more decompositions exist.
