Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972878, here are decompositions:
- 11 + 4294972867 = 4294972878
- 17 + 4294972861 = 4294972878
- 19 + 4294972859 = 4294972878
- 71 + 4294972807 = 4294972878
- 89 + 4294972789 = 4294972878
- 127 + 4294972751 = 4294972878
- 151 + 4294972727 = 4294972878
- 269 + 4294972609 = 4294972878
Showing the first eight; more decompositions exist.
