Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26420, here are decompositions:
- 3 + 26417 = 26420
- 13 + 26407 = 26420
- 73 + 26347 = 26420
- 103 + 26317 = 26420
- 127 + 26293 = 26420
- 157 + 26263 = 26420
- 193 + 26227 = 26420
- 211 + 26209 = 26420
Showing the first eight; more decompositions exist.
