Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541322, here are decompositions:
- 41 + 31541281 = 31541322
- 53 + 31541269 = 31541322
- 79 + 31541243 = 31541322
- 89 + 31541233 = 31541322
- 149 + 31541173 = 31541322
- 181 + 31541141 = 31541322
- 193 + 31541129 = 31541322
- 251 + 31541071 = 31541322
Showing the first eight; more decompositions exist.
