Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65566, here are decompositions:
- 3 + 65563 = 65566
- 23 + 65543 = 65566
- 29 + 65537 = 65566
- 47 + 65519 = 65566
- 173 + 65393 = 65566
- 239 + 65327 = 65566
- 257 + 65309 = 65566
- 353 + 65213 = 65566
Showing the first eight; more decompositions exist.
