Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66938, here are decompositions:
- 7 + 66931 = 66938
- 19 + 66919 = 66938
- 61 + 66877 = 66938
- 97 + 66841 = 66938
- 199 + 66739 = 66938
- 241 + 66697 = 66938
- 337 + 66601 = 66938
- 367 + 66571 = 66938
Showing the first eight; more decompositions exist.
