Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12984, here are decompositions:
- 5 + 12979 = 12984
- 11 + 12973 = 12984
- 17 + 12967 = 12984
- 31 + 12953 = 12984
- 43 + 12941 = 12984
- 61 + 12923 = 12984
- 67 + 12917 = 12984
- 73 + 12911 = 12984
Showing the first eight; more decompositions exist.
