Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526230, here are decompositions:
- 3 + 31526227 = 31526230
- 17 + 31526213 = 31526230
- 23 + 31526207 = 31526230
- 41 + 31526189 = 31526230
- 89 + 31526141 = 31526230
- 167 + 31526063 = 31526230
- 173 + 31526057 = 31526230
- 179 + 31526051 = 31526230
Showing the first eight; more decompositions exist.
