Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526470, here are decompositions:
- 47 + 31526423 = 31526470
- 83 + 31526387 = 31526470
- 197 + 31526273 = 31526470
- 257 + 31526213 = 31526470
- 263 + 31526207 = 31526470
- 281 + 31526189 = 31526470
- 383 + 31526087 = 31526470
- 401 + 31526069 = 31526470
Showing the first eight; more decompositions exist.
