Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16742, here are decompositions:
- 13 + 16729 = 16742
- 43 + 16699 = 16742
- 109 + 16633 = 16742
- 139 + 16603 = 16742
- 181 + 16561 = 16742
- 223 + 16519 = 16742
- 331 + 16411 = 16742
- 373 + 16369 = 16742
Showing the first eight; more decompositions exist.
