Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546080, here are decompositions:
- 11 + 31546069 = 31546080
- 17 + 31546063 = 31546080
- 61 + 31546019 = 31546080
- 67 + 31546013 = 31546080
- 73 + 31546007 = 31546080
- 89 + 31545991 = 31546080
- 127 + 31545953 = 31546080
- 157 + 31545923 = 31546080
Showing the first eight; more decompositions exist.
