Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549500, here are decompositions:
- 61 + 31549439 = 31549500
- 89 + 31549411 = 31549500
- 97 + 31549403 = 31549500
- 109 + 31549391 = 31549500
- 127 + 31549373 = 31549500
- 163 + 31549337 = 31549500
- 173 + 31549327 = 31549500
- 223 + 31549277 = 31549500
Showing the first eight; more decompositions exist.
