Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967988, here are decompositions:
- 5 + 4294967983 = 4294967988
- 11 + 4294967977 = 4294967988
- 19 + 4294967969 = 4294967988
- 97 + 4294967891 = 4294967988
- 127 + 4294967861 = 4294967988
- 131 + 4294967857 = 4294967988
- 167 + 4294967821 = 4294967988
- 191 + 4294967797 = 4294967988
Showing the first eight; more decompositions exist.
