Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972874, here are decompositions:
- 7 + 4294972867 = 4294972874
- 13 + 4294972861 = 4294972874
- 67 + 4294972807 = 4294972874
- 211 + 4294972663 = 4294972874
- 271 + 4294972603 = 4294972874
- 307 + 4294972567 = 4294972874
- 433 + 4294972441 = 4294972874
- 463 + 4294972411 = 4294972874
Showing the first eight; more decompositions exist.
