Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25520, here are decompositions:
- 67 + 25453 = 25520
- 73 + 25447 = 25520
- 97 + 25423 = 25520
- 109 + 25411 = 25520
- 163 + 25357 = 25520
- 181 + 25339 = 25520
- 199 + 25321 = 25520
- 211 + 25309 = 25520
Showing the first eight; more decompositions exist.
