Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532100, here are decompositions:
- 11 + 31532089 = 31532100
- 29 + 31532071 = 31532100
- 37 + 31532063 = 31532100
- 79 + 31532021 = 31532100
- 97 + 31532003 = 31532100
- 179 + 31531921 = 31532100
- 191 + 31531909 = 31532100
- 283 + 31531817 = 31532100
Showing the first eight; more decompositions exist.
