Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539954, here are decompositions:
- 23 + 31539931 = 31539954
- 53 + 31539901 = 31539954
- 97 + 31539857 = 31539954
- 137 + 31539817 = 31539954
- 191 + 31539763 = 31539954
- 197 + 31539757 = 31539954
- 227 + 31539727 = 31539954
- 241 + 31539713 = 31539954
Showing the first eight; more decompositions exist.
