Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526242, here are decompositions:
- 3 + 31526239 = 31526242
- 29 + 31526213 = 31526242
- 53 + 31526189 = 31526242
- 101 + 31526141 = 31526242
- 173 + 31526069 = 31526242
- 179 + 31526063 = 31526242
- 191 + 31526051 = 31526242
- 353 + 31525889 = 31526242
Showing the first eight; more decompositions exist.
