Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25944, here are decompositions:
- 5 + 25939 = 25944
- 11 + 25933 = 25944
- 13 + 25931 = 25944
- 31 + 25913 = 25944
- 41 + 25903 = 25944
- 71 + 25873 = 25944
- 97 + 25847 = 25944
- 103 + 25841 = 25944
Showing the first eight; more decompositions exist.
