Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526438, here are decompositions:
- 7 + 31526431 = 31526438
- 19 + 31526419 = 31526438
- 67 + 31526371 = 31526438
- 79 + 31526359 = 31526438
- 157 + 31526281 = 31526438
- 199 + 31526239 = 31526438
- 211 + 31526227 = 31526438
- 241 + 31526197 = 31526438
Showing the first eight; more decompositions exist.
