Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25550, here are decompositions:
- 13 + 25537 = 25550
- 79 + 25471 = 25550
- 97 + 25453 = 25550
- 103 + 25447 = 25550
- 127 + 25423 = 25550
- 139 + 25411 = 25550
- 193 + 25357 = 25550
- 211 + 25339 = 25550
Showing the first eight; more decompositions exist.
