Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532960, here are decompositions:
- 37 + 31532923 = 31532960
- 61 + 31532899 = 31532960
- 79 + 31532881 = 31532960
- 97 + 31532863 = 31532960
- 127 + 31532833 = 31532960
- 211 + 31532749 = 31532960
- 223 + 31532737 = 31532960
- 307 + 31532653 = 31532960
Showing the first eight; more decompositions exist.
