Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526842, here are decompositions:
- 23 + 31526819 = 31526842
- 71 + 31526771 = 31526842
- 89 + 31526753 = 31526842
- 173 + 31526669 = 31526842
- 239 + 31526603 = 31526842
- 353 + 31526489 = 31526842
- 419 + 31526423 = 31526842
- 491 + 31526351 = 31526842
Showing the first eight; more decompositions exist.
