Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972868, here are decompositions:
- 7 + 4294972861 = 4294972868
- 61 + 4294972807 = 4294972868
- 79 + 4294972789 = 4294972868
- 211 + 4294972657 = 4294972868
- 457 + 4294972411 = 4294972868
- 577 + 4294972291 = 4294972868
- 601 + 4294972267 = 4294972868
- 631 + 4294972237 = 4294972868
Showing the first eight; more decompositions exist.
