Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526316, here are decompositions:
- 43 + 31526273 = 31526316
- 89 + 31526227 = 31526316
- 103 + 31526213 = 31526316
- 109 + 31526207 = 31526316
- 127 + 31526189 = 31526316
- 229 + 31526087 = 31526316
- 233 + 31526083 = 31526316
- 359 + 31525957 = 31526316
Showing the first eight; more decompositions exist.
