Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544816, here are decompositions:
- 67 + 31544749 = 31544816
- 97 + 31544719 = 31544816
- 103 + 31544713 = 31544816
- 229 + 31544587 = 31544816
- 283 + 31544533 = 31544816
- 307 + 31544509 = 31544816
- 727 + 31544089 = 31544816
- 739 + 31544077 = 31544816
Showing the first eight; more decompositions exist.
