Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972880, here are decompositions:
- 13 + 4294972867 = 4294972880
- 19 + 4294972861 = 4294972880
- 73 + 4294972807 = 4294972880
- 223 + 4294972657 = 4294972880
- 271 + 4294972609 = 4294972880
- 277 + 4294972603 = 4294972880
- 313 + 4294972567 = 4294972880
- 439 + 4294972441 = 4294972880
Showing the first eight; more decompositions exist.
