Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972782, here are decompositions:
- 31 + 4294972751 = 4294972782
- 173 + 4294972609 = 4294972782
- 179 + 4294972603 = 4294972782
- 223 + 4294972559 = 4294972782
- 349 + 4294972433 = 4294972782
- 389 + 4294972393 = 4294972782
- 431 + 4294972351 = 4294972782
- 449 + 4294972333 = 4294972782
Showing the first eight; more decompositions exist.
