Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549100, here are decompositions:
- 13 + 31549087 = 31549100
- 19 + 31549081 = 31549100
- 61 + 31549039 = 31549100
- 103 + 31548997 = 31549100
- 139 + 31548961 = 31549100
- 229 + 31548871 = 31549100
- 277 + 31548823 = 31549100
- 283 + 31548817 = 31549100
Showing the first eight; more decompositions exist.
