Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533102, here are decompositions:
- 5 + 31533097 = 31533102
- 11 + 31533091 = 31533102
- 89 + 31533013 = 31533102
- 101 + 31533001 = 31533102
- 103 + 31532999 = 31533102
- 131 + 31532971 = 31533102
- 163 + 31532939 = 31533102
- 179 + 31532923 = 31533102
Showing the first eight; more decompositions exist.
