Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19766, here are decompositions:
- 3 + 19763 = 19766
- 7 + 19759 = 19766
- 13 + 19753 = 19766
- 67 + 19699 = 19766
- 79 + 19687 = 19766
- 157 + 19609 = 19766
- 163 + 19603 = 19766
- 223 + 19543 = 19766
Showing the first eight; more decompositions exist.
