Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972668, here are decompositions:
- 5 + 4294972663 = 4294972668
- 11 + 4294972657 = 4294972668
- 59 + 4294972609 = 4294972668
- 89 + 4294972579 = 4294972668
- 101 + 4294972567 = 4294972668
- 109 + 4294972559 = 4294972668
- 227 + 4294972441 = 4294972668
- 257 + 4294972411 = 4294972668
Showing the first eight; more decompositions exist.
