Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66968, here are decompositions:
- 19 + 66949 = 66968
- 37 + 66931 = 66968
- 79 + 66889 = 66968
- 127 + 66841 = 66968
- 229 + 66739 = 66968
- 271 + 66697 = 66968
- 367 + 66601 = 66968
- 397 + 66571 = 66968
Showing the first eight; more decompositions exist.
