Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67998, here are decompositions:
- 5 + 67993 = 67998
- 11 + 67987 = 67998
- 19 + 67979 = 67998
- 31 + 67967 = 67998
- 37 + 67961 = 67998
- 41 + 67957 = 67998
- 59 + 67939 = 67998
- 67 + 67931 = 67998
Showing the first eight; more decompositions exist.
