Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539960, here are decompositions:
- 29 + 31539931 = 31539960
- 59 + 31539901 = 31539960
- 71 + 31539889 = 31539960
- 97 + 31539863 = 31539960
- 103 + 31539857 = 31539960
- 139 + 31539821 = 31539960
- 197 + 31539763 = 31539960
- 223 + 31539737 = 31539960
Showing the first eight; more decompositions exist.
