Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533964, here are decompositions:
- 5 + 31533959 = 31533964
- 41 + 31533923 = 31533964
- 53 + 31533911 = 31533964
- 131 + 31533833 = 31533964
- 173 + 31533791 = 31533964
- 191 + 31533773 = 31533964
- 257 + 31533707 = 31533964
- 353 + 31533611 = 31533964
Showing the first eight; more decompositions exist.
