Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973072, here are decompositions:
- 3 + 4294973069 = 4294973072
- 211 + 4294972861 = 4294973072
- 283 + 4294972789 = 4294973072
- 409 + 4294972663 = 4294973072
- 463 + 4294972609 = 4294973072
- 631 + 4294972441 = 4294973072
- 661 + 4294972411 = 4294973072
- 739 + 4294972333 = 4294973072
Showing the first eight; more decompositions exist.
