Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25998, here are decompositions:
- 17 + 25981 = 25998
- 29 + 25969 = 25998
- 47 + 25951 = 25998
- 59 + 25939 = 25998
- 67 + 25931 = 25998
- 79 + 25919 = 25998
- 109 + 25889 = 25998
- 131 + 25867 = 25998
Showing the first eight; more decompositions exist.
