Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532300, here are decompositions:
- 31 + 31532269 = 31532300
- 73 + 31532227 = 31532300
- 97 + 31532203 = 31532300
- 211 + 31532089 = 31532300
- 229 + 31532071 = 31532300
- 379 + 31531921 = 31532300
- 487 + 31531813 = 31532300
- 661 + 31531639 = 31532300
Showing the first eight; more decompositions exist.
