Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26128, here are decompositions:
- 17 + 26111 = 26128
- 29 + 26099 = 26128
- 107 + 26021 = 26128
- 131 + 25997 = 26128
- 197 + 25931 = 26128
- 239 + 25889 = 26128
- 281 + 25847 = 26128
- 449 + 25679 = 26128
Showing the first eight; more decompositions exist.
