Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972078, here are decompositions:
- 17 + 4294972061 = 4294972078
- 29 + 4294972049 = 4294972078
- 41 + 4294972037 = 4294972078
- 149 + 4294971929 = 4294972078
- 521 + 4294971557 = 4294972078
- 587 + 4294971491 = 4294972078
- 647 + 4294971431 = 4294972078
- 701 + 4294971377 = 4294972078
Showing the first eight; more decompositions exist.
