Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65424, here are decompositions:
- 5 + 65419 = 65424
- 11 + 65413 = 65424
- 17 + 65407 = 65424
- 31 + 65393 = 65424
- 43 + 65381 = 65424
- 53 + 65371 = 65424
- 67 + 65357 = 65424
- 71 + 65353 = 65424
Showing the first eight; more decompositions exist.
