Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971728, here are decompositions:
- 337 + 4294971391 = 4294971728
- 349 + 4294971379 = 4294971728
- 379 + 4294971349 = 4294971728
- 577 + 4294971151 = 4294971728
- 601 + 4294971127 = 4294971728
- 631 + 4294971097 = 4294971728
- 967 + 4294970761 = 4294971728
- 1381 + 4294970347 = 4294971728
Showing the first eight; more decompositions exist.
