Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972870, here are decompositions:
- 3 + 4294972867 = 4294972870
- 11 + 4294972859 = 4294972870
- 47 + 4294972823 = 4294972870
- 257 + 4294972613 = 4294972870
- 311 + 4294972559 = 4294972870
- 389 + 4294972481 = 4294972870
- 449 + 4294972421 = 4294972870
- 563 + 4294972307 = 4294972870
Showing the first eight; more decompositions exist.
