Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546160, here are decompositions:
- 7 + 31546153 = 31546160
- 31 + 31546129 = 31546160
- 97 + 31546063 = 31546160
- 241 + 31545919 = 31546160
- 397 + 31545763 = 31546160
- 421 + 31545739 = 31546160
- 661 + 31545499 = 31546160
- 673 + 31545487 = 31546160
Showing the first eight; more decompositions exist.
