Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533936, here are decompositions:
- 13 + 31533923 = 31533936
- 17 + 31533919 = 31533936
- 89 + 31533847 = 31533936
- 97 + 31533839 = 31533936
- 103 + 31533833 = 31533936
- 107 + 31533829 = 31533936
- 113 + 31533823 = 31533936
- 163 + 31533773 = 31533936
Showing the first eight; more decompositions exist.
