Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972838, here are decompositions:
- 31 + 4294972807 = 4294972838
- 181 + 4294972657 = 4294972838
- 229 + 4294972609 = 4294972838
- 271 + 4294972567 = 4294972838
- 397 + 4294972441 = 4294972838
- 487 + 4294972351 = 4294972838
- 547 + 4294972291 = 4294972838
- 571 + 4294972267 = 4294972838
Showing the first eight; more decompositions exist.
