Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971638, here are decompositions:
- 31 + 4294971607 = 4294971638
- 271 + 4294971367 = 4294971638
- 337 + 4294971301 = 4294971638
- 439 + 4294971199 = 4294971638
- 487 + 4294971151 = 4294971638
- 541 + 4294971097 = 4294971638
- 877 + 4294970761 = 4294971638
- 1069 + 4294970569 = 4294971638
Showing the first eight; more decompositions exist.
