Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544948, here are decompositions:
- 7 + 31544941 = 31544948
- 199 + 31544749 = 31544948
- 229 + 31544719 = 31544948
- 397 + 31544551 = 31544948
- 439 + 31544509 = 31544948
- 577 + 31544371 = 31544948
- 601 + 31544347 = 31544948
- 727 + 31544221 = 31544948
Showing the first eight; more decompositions exist.
