Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533060, here are decompositions:
- 47 + 31533013 = 31533060
- 59 + 31533001 = 31533060
- 61 + 31532999 = 31533060
- 79 + 31532981 = 31533060
- 89 + 31532971 = 31533060
- 101 + 31532959 = 31533060
- 137 + 31532923 = 31533060
- 179 + 31532881 = 31533060
Showing the first eight; more decompositions exist.
