Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526478, here are decompositions:
- 47 + 31526431 = 31526478
- 59 + 31526419 = 31526478
- 89 + 31526389 = 31526478
- 107 + 31526371 = 31526478
- 127 + 31526351 = 31526478
- 197 + 31526281 = 31526478
- 239 + 31526239 = 31526478
- 251 + 31526227 = 31526478
Showing the first eight; more decompositions exist.
