Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533030, here are decompositions:
- 17 + 31533013 = 31533030
- 29 + 31533001 = 31533030
- 31 + 31532999 = 31533030
- 59 + 31532971 = 31533030
- 71 + 31532959 = 31533030
- 107 + 31532923 = 31533030
- 131 + 31532899 = 31533030
- 149 + 31532881 = 31533030
Showing the first eight; more decompositions exist.
