Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525986, here are decompositions:
- 5 + 31525981 = 31525986
- 29 + 31525957 = 31525986
- 59 + 31525927 = 31525986
- 67 + 31525919 = 31525986
- 73 + 31525913 = 31525986
- 83 + 31525903 = 31525986
- 97 + 31525889 = 31525986
- 137 + 31525849 = 31525986
Showing the first eight; more decompositions exist.
