Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971858, here are decompositions:
- 17 + 4294971841 = 4294971858
- 29 + 4294971829 = 4294971858
- 251 + 4294971607 = 4294971858
- 367 + 4294971491 = 4294971858
- 389 + 4294971469 = 4294971858
- 467 + 4294971391 = 4294971858
- 479 + 4294971379 = 4294971858
- 491 + 4294971367 = 4294971858
Showing the first eight; more decompositions exist.
