Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526678, here are decompositions:
- 31 + 31526647 = 31526678
- 61 + 31526617 = 31526678
- 151 + 31526527 = 31526678
- 181 + 31526497 = 31526678
- 307 + 31526371 = 31526678
- 397 + 31526281 = 31526678
- 439 + 31526239 = 31526678
- 457 + 31526221 = 31526678
Showing the first eight; more decompositions exist.
