Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971538, here are decompositions:
- 41 + 4294971497 = 4294971538
- 47 + 4294971491 = 4294971538
- 107 + 4294971431 = 4294971538
- 149 + 4294971389 = 4294971538
- 269 + 4294971269 = 4294971538
- 311 + 4294971227 = 4294971538
- 317 + 4294971221 = 4294971538
- 461 + 4294971077 = 4294971538
Showing the first eight; more decompositions exist.
