Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971640, here are decompositions:
- 83 + 4294971557 = 4294971640
- 137 + 4294971503 = 4294971640
- 149 + 4294971491 = 4294971640
- 251 + 4294971389 = 4294971640
- 263 + 4294971377 = 4294971640
- 317 + 4294971323 = 4294971640
- 419 + 4294971221 = 4294971640
- 431 + 4294971209 = 4294971640
Showing the first eight; more decompositions exist.
