Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13850, here are decompositions:
- 19 + 13831 = 13850
- 43 + 13807 = 13850
- 61 + 13789 = 13850
- 127 + 13723 = 13850
- 139 + 13711 = 13850
- 157 + 13693 = 13850
- 163 + 13687 = 13850
- 181 + 13669 = 13850
Showing the first eight; more decompositions exist.
