Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527250, here are decompositions:
- 3 + 31527247 = 31527250
- 17 + 31527233 = 31527250
- 59 + 31527191 = 31527250
- 101 + 31527149 = 31527250
- 107 + 31527143 = 31527250
- 173 + 31527077 = 31527250
- 233 + 31527017 = 31527250
- 239 + 31527011 = 31527250
Showing the first eight; more decompositions exist.
