Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967840, here are decompositions:
- 19 + 4294967821 = 4294967840
- 43 + 4294967797 = 4294967840
- 61 + 4294967779 = 4294967840
- 139 + 4294967701 = 4294967840
- 271 + 4294967569 = 4294967840
- 277 + 4294967563 = 4294967840
- 463 + 4294967377 = 4294967840
- 643 + 4294967197 = 4294967840
Showing the first eight; more decompositions exist.
