Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532112, here are decompositions:
- 23 + 31532089 = 31532112
- 41 + 31532071 = 31532112
- 109 + 31532003 = 31532112
- 181 + 31531931 = 31532112
- 191 + 31531921 = 31532112
- 229 + 31531883 = 31532112
- 433 + 31531679 = 31532112
- 463 + 31531649 = 31532112
Showing the first eight; more decompositions exist.
