Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967978, here are decompositions:
- 157 + 4294967821 = 4294967978
- 181 + 4294967797 = 4294967978
- 199 + 4294967779 = 4294967978
- 277 + 4294967701 = 4294967978
- 409 + 4294967569 = 4294967978
- 439 + 4294967539 = 4294967978
- 601 + 4294967377 = 4294967978
- 607 + 4294967371 = 4294967978
Showing the first eight; more decompositions exist.
