Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526638, here are decompositions:
- 5 + 31526633 = 31526638
- 149 + 31526489 = 31526638
- 251 + 31526387 = 31526638
- 431 + 31526207 = 31526638
- 449 + 31526189 = 31526638
- 569 + 31526069 = 31526638
- 587 + 31526051 = 31526638
- 617 + 31526021 = 31526638
Showing the first eight; more decompositions exist.
