Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25984, here are decompositions:
- 3 + 25981 = 25984
- 41 + 25943 = 25984
- 53 + 25931 = 25984
- 71 + 25913 = 25984
- 137 + 25847 = 25984
- 191 + 25793 = 25984
- 251 + 25733 = 25984
- 281 + 25703 = 25984
Showing the first eight; more decompositions exist.
