Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26642, here are decompositions:
- 103 + 26539 = 26642
- 163 + 26479 = 26642
- 193 + 26449 = 26642
- 211 + 26431 = 26642
- 271 + 26371 = 26642
- 349 + 26293 = 26642
- 379 + 26263 = 26642
- 433 + 26209 = 26642
Showing the first eight; more decompositions exist.
