Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533852, here are decompositions:
- 5 + 31533847 = 31533852
- 13 + 31533839 = 31533852
- 19 + 31533833 = 31533852
- 23 + 31533829 = 31533852
- 29 + 31533823 = 31533852
- 61 + 31533791 = 31533852
- 79 + 31533773 = 31533852
- 83 + 31533769 = 31533852
Showing the first eight; more decompositions exist.
