Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294969978, here are decompositions:
- 29 + 4294969949 = 4294969978
- 71 + 4294969907 = 4294969978
- 107 + 4294969871 = 4294969978
- 149 + 4294969829 = 4294969978
- 197 + 4294969781 = 4294969978
- 239 + 4294969739 = 4294969978
- 251 + 4294969727 = 4294969978
- 311 + 4294969667 = 4294969978
Showing the first eight; more decompositions exist.
