Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539024, here are decompositions:
- 17 + 31539007 = 31539024
- 37 + 31538987 = 31539024
- 73 + 31538951 = 31539024
- 137 + 31538887 = 31539024
- 197 + 31538827 = 31539024
- 271 + 31538753 = 31539024
- 281 + 31538743 = 31539024
- 311 + 31538713 = 31539024
Showing the first eight; more decompositions exist.
