Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972866, here are decompositions:
- 5 + 4294972861 = 4294972866
- 7 + 4294972859 = 4294972866
- 43 + 4294972823 = 4294972866
- 59 + 4294972807 = 4294972866
- 73 + 4294972793 = 4294972866
- 139 + 4294972727 = 4294972866
- 257 + 4294972609 = 4294972866
- 263 + 4294972603 = 4294972866
Showing the first eight; more decompositions exist.
