Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528398, here are decompositions:
- 61 + 31528337 = 31528398
- 71 + 31528327 = 31528398
- 107 + 31528291 = 31528398
- 131 + 31528267 = 31528398
- 157 + 31528241 = 31528398
- 191 + 31528207 = 31528398
- 227 + 31528171 = 31528398
- 229 + 31528169 = 31528398
Showing the first eight; more decompositions exist.
