Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532976, here are decompositions:
- 5 + 31532971 = 31532976
- 17 + 31532959 = 31532976
- 37 + 31532939 = 31532976
- 53 + 31532923 = 31532976
- 103 + 31532873 = 31532976
- 109 + 31532867 = 31532976
- 113 + 31532863 = 31532976
- 199 + 31532777 = 31532976
Showing the first eight; more decompositions exist.
