Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16562, here are decompositions:
- 43 + 16519 = 16562
- 109 + 16453 = 16562
- 151 + 16411 = 16562
- 181 + 16381 = 16562
- 193 + 16369 = 16562
- 199 + 16363 = 16562
- 223 + 16339 = 16562
- 229 + 16333 = 16562
Showing the first eight; more decompositions exist.
