Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26138, here are decompositions:
- 19 + 26119 = 26138
- 31 + 26107 = 26138
- 97 + 26041 = 26138
- 109 + 26029 = 26138
- 139 + 25999 = 26138
- 157 + 25981 = 26138
- 199 + 25939 = 26138
- 271 + 25867 = 26138
Showing the first eight; more decompositions exist.
