Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20676, here are decompositions:
- 13 + 20663 = 20676
- 37 + 20639 = 20676
- 83 + 20593 = 20676
- 113 + 20563 = 20676
- 127 + 20549 = 20676
- 167 + 20509 = 20676
- 193 + 20483 = 20676
- 197 + 20479 = 20676
Showing the first eight; more decompositions exist.
