Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527110, here are decompositions:
- 3 + 31527107 = 31527110
- 157 + 31526953 = 31527110
- 211 + 31526899 = 31527110
- 229 + 31526881 = 31527110
- 337 + 31526773 = 31527110
- 379 + 31526731 = 31527110
- 397 + 31526713 = 31527110
- 421 + 31526689 = 31527110
Showing the first eight; more decompositions exist.
