Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525678, here are decompositions:
- 29 + 31525649 = 31525678
- 71 + 31525607 = 31525678
- 89 + 31525589 = 31525678
- 179 + 31525499 = 31525678
- 257 + 31525421 = 31525678
- 281 + 31525397 = 31525678
- 311 + 31525367 = 31525678
- 347 + 31525331 = 31525678
Showing the first eight; more decompositions exist.
