Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528406, here are decompositions:
- 43 + 31528363 = 31528406
- 79 + 31528327 = 31528406
- 127 + 31528279 = 31528406
- 139 + 31528267 = 31528406
- 193 + 31528213 = 31528406
- 199 + 31528207 = 31528406
- 313 + 31528093 = 31528406
- 337 + 31528069 = 31528406
Showing the first eight; more decompositions exist.
