Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546072, here are decompositions:
- 3 + 31546069 = 31546072
- 53 + 31546019 = 31546072
- 59 + 31546013 = 31546072
- 113 + 31545959 = 31546072
- 149 + 31545923 = 31546072
- 359 + 31545713 = 31546072
- 431 + 31545641 = 31546072
- 443 + 31545629 = 31546072
Showing the first eight; more decompositions exist.
