Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972842, here are decompositions:
- 19 + 4294972823 = 4294972842
- 53 + 4294972789 = 4294972842
- 179 + 4294972663 = 4294972842
- 229 + 4294972613 = 4294972842
- 233 + 4294972609 = 4294972842
- 239 + 4294972603 = 4294972842
- 263 + 4294972579 = 4294972842
- 283 + 4294972559 = 4294972842
Showing the first eight; more decompositions exist.
