Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972928, here are decompositions:
- 31 + 4294972897 = 4294972928
- 61 + 4294972867 = 4294972928
- 67 + 4294972861 = 4294972928
- 139 + 4294972789 = 4294972928
- 271 + 4294972657 = 4294972928
- 349 + 4294972579 = 4294972928
- 487 + 4294972441 = 4294972928
- 577 + 4294972351 = 4294972928
Showing the first eight; more decompositions exist.
