Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972772, here are decompositions:
- 109 + 4294972663 = 4294972772
- 163 + 4294972609 = 4294972772
- 193 + 4294972579 = 4294972772
- 331 + 4294972441 = 4294972772
- 379 + 4294972393 = 4294972772
- 421 + 4294972351 = 4294972772
- 439 + 4294972333 = 4294972772
- 709 + 4294972063 = 4294972772
Showing the first eight; more decompositions exist.
