Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16492, here are decompositions:
- 5 + 16487 = 16492
- 11 + 16481 = 16492
- 41 + 16451 = 16492
- 59 + 16433 = 16492
- 71 + 16421 = 16492
- 131 + 16361 = 16492
- 173 + 16319 = 16492
- 191 + 16301 = 16492
Showing the first eight; more decompositions exist.
