Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66908, here are decompositions:
- 19 + 66889 = 66908
- 31 + 66877 = 66908
- 67 + 66841 = 66908
- 157 + 66751 = 66908
- 211 + 66697 = 66908
- 307 + 66601 = 66908
- 337 + 66571 = 66908
- 367 + 66541 = 66908
Showing the first eight; more decompositions exist.
