Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61440, here are decompositions:
- 23 + 61417 = 61440
- 31 + 61409 = 61440
- 37 + 61403 = 61440
- 59 + 61381 = 61440
- 61 + 61379 = 61440
- 83 + 61357 = 61440
- 97 + 61343 = 61440
- 101 + 61339 = 61440
Showing the first eight; more decompositions exist.
