Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545616, here are decompositions:
- 5 + 31545611 = 31545616
- 17 + 31545599 = 31545616
- 293 + 31545323 = 31545616
- 317 + 31545299 = 31545616
- 383 + 31545233 = 31545616
- 593 + 31545023 = 31545616
- 647 + 31544969 = 31545616
- 653 + 31544963 = 31545616
Showing the first eight; more decompositions exist.
