Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533194, here are decompositions:
- 3 + 31533191 = 31533194
- 61 + 31533133 = 31533194
- 67 + 31533127 = 31533194
- 97 + 31533097 = 31533194
- 103 + 31533091 = 31533194
- 181 + 31533013 = 31533194
- 193 + 31533001 = 31533194
- 223 + 31532971 = 31533194
Showing the first eight; more decompositions exist.
