Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26864, here are decompositions:
- 3 + 26861 = 26864
- 31 + 26833 = 26864
- 43 + 26821 = 26864
- 127 + 26737 = 26864
- 151 + 26713 = 26864
- 163 + 26701 = 26864
- 181 + 26683 = 26864
- 223 + 26641 = 26864
Showing the first eight; more decompositions exist.
