Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16542, here are decompositions:
- 13 + 16529 = 16542
- 23 + 16519 = 16542
- 61 + 16481 = 16542
- 89 + 16453 = 16542
- 109 + 16433 = 16542
- 131 + 16411 = 16542
- 173 + 16369 = 16542
- 179 + 16363 = 16542
Showing the first eight; more decompositions exist.
