Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971808, here are decompositions:
- 251 + 4294971557 = 4294971808
- 311 + 4294971497 = 4294971808
- 317 + 4294971491 = 4294971808
- 419 + 4294971389 = 4294971808
- 431 + 4294971377 = 4294971808
- 587 + 4294971221 = 4294971808
- 599 + 4294971209 = 4294971808
- 929 + 4294970879 = 4294971808
Showing the first eight; more decompositions exist.
