Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65340, here are decompositions:
- 13 + 65327 = 65340
- 17 + 65323 = 65340
- 31 + 65309 = 65340
- 47 + 65293 = 65340
- 53 + 65287 = 65340
- 71 + 65269 = 65340
- 73 + 65267 = 65340
- 83 + 65257 = 65340
Showing the first eight; more decompositions exist.
