Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533616, here are decompositions:
- 3 + 31533613 = 31533616
- 5 + 31533611 = 31533616
- 17 + 31533599 = 31533616
- 29 + 31533587 = 31533616
- 53 + 31533563 = 31533616
- 83 + 31533533 = 31533616
- 167 + 31533449 = 31533616
- 227 + 31533389 = 31533616
Showing the first eight; more decompositions exist.
