Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978886, here are decompositions:
- 13 + 4294978873 = 4294978886
- 19 + 4294978867 = 4294978886
- 109 + 4294978777 = 4294978886
- 157 + 4294978729 = 4294978886
- 397 + 4294978489 = 4294978886
- 487 + 4294978399 = 4294978886
- 577 + 4294978309 = 4294978886
- 739 + 4294978147 = 4294978886
Showing the first eight; more decompositions exist.
