Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16538, here are decompositions:
- 19 + 16519 = 16538
- 61 + 16477 = 16538
- 127 + 16411 = 16538
- 157 + 16381 = 16538
- 199 + 16339 = 16538
- 271 + 16267 = 16538
- 307 + 16231 = 16538
- 349 + 16189 = 16538
Showing the first eight; more decompositions exist.
