Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67986, here are decompositions:
- 7 + 67979 = 67986
- 19 + 67967 = 67986
- 29 + 67957 = 67986
- 43 + 67943 = 67986
- 47 + 67939 = 67986
- 53 + 67933 = 67986
- 59 + 67927 = 67986
- 103 + 67883 = 67986
Showing the first eight; more decompositions exist.
