Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544970, here are decompositions:
- 7 + 31544963 = 31544970
- 29 + 31544941 = 31544970
- 47 + 31544923 = 31544970
- 71 + 31544899 = 31544970
- 113 + 31544857 = 31544970
- 151 + 31544819 = 31544970
- 199 + 31544771 = 31544970
- 211 + 31544759 = 31544970
Showing the first eight; more decompositions exist.
