Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526672, here are decompositions:
- 3 + 31526669 = 31526672
- 109 + 31526563 = 31526672
- 139 + 31526533 = 31526672
- 241 + 31526431 = 31526672
- 283 + 31526389 = 31526672
- 313 + 31526359 = 31526672
- 433 + 31526239 = 31526672
- 691 + 31525981 = 31526672
Showing the first eight; more decompositions exist.
