Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65572, here are decompositions:
- 29 + 65543 = 65572
- 53 + 65519 = 65572
- 149 + 65423 = 65572
- 179 + 65393 = 65572
- 191 + 65381 = 65572
- 263 + 65309 = 65572
- 359 + 65213 = 65572
- 389 + 65183 = 65572
Showing the first eight; more decompositions exist.
