Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533700, here are decompositions:
- 41 + 31533659 = 31533700
- 59 + 31533641 = 31533700
- 89 + 31533611 = 31533700
- 101 + 31533599 = 31533700
- 113 + 31533587 = 31533700
- 137 + 31533563 = 31533700
- 167 + 31533533 = 31533700
- 239 + 31533461 = 31533700
Showing the first eight; more decompositions exist.
