Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16802, here are decompositions:
- 43 + 16759 = 16802
- 61 + 16741 = 16802
- 73 + 16729 = 16802
- 103 + 16699 = 16802
- 109 + 16693 = 16802
- 151 + 16651 = 16802
- 199 + 16603 = 16802
- 229 + 16573 = 16802
Showing the first eight; more decompositions exist.
