Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533996, here are decompositions:
- 17 + 31533979 = 31533996
- 29 + 31533967 = 31533996
- 37 + 31533959 = 31533996
- 47 + 31533949 = 31533996
- 73 + 31533923 = 31533996
- 149 + 31533847 = 31533996
- 157 + 31533839 = 31533996
- 163 + 31533833 = 31533996
Showing the first eight; more decompositions exist.
