Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51566, here are decompositions:
- 3 + 51563 = 51566
- 79 + 51487 = 51566
- 127 + 51439 = 51566
- 139 + 51427 = 51566
- 223 + 51343 = 51566
- 283 + 51283 = 51566
- 337 + 51229 = 51566
- 349 + 51217 = 51566
Showing the first eight; more decompositions exist.
