Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526212, here are decompositions:
- 5 + 31526207 = 31526212
- 23 + 31526189 = 31526212
- 71 + 31526141 = 31526212
- 149 + 31526063 = 31526212
- 191 + 31526021 = 31526212
- 293 + 31525919 = 31526212
- 401 + 31525811 = 31526212
- 449 + 31525763 = 31526212
Showing the first eight; more decompositions exist.
