Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16878, here are decompositions:
- 7 + 16871 = 16878
- 47 + 16831 = 16878
- 67 + 16811 = 16878
- 131 + 16747 = 16878
- 137 + 16741 = 16878
- 149 + 16729 = 16878
- 179 + 16699 = 16878
- 227 + 16651 = 16878
Showing the first eight; more decompositions exist.
