Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971668, here are decompositions:
- 61 + 4294971607 = 4294971668
- 199 + 4294971469 = 4294971668
- 277 + 4294971391 = 4294971668
- 367 + 4294971301 = 4294971668
- 499 + 4294971169 = 4294971668
- 541 + 4294971127 = 4294971668
- 571 + 4294971097 = 4294971668
- 829 + 4294970839 = 4294971668
Showing the first eight; more decompositions exist.
