Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67686, here are decompositions:
- 7 + 67679 = 67686
- 67 + 67619 = 67686
- 79 + 67607 = 67686
- 97 + 67589 = 67686
- 107 + 67579 = 67686
- 109 + 67577 = 67686
- 127 + 67559 = 67686
- 139 + 67547 = 67686
Showing the first eight; more decompositions exist.
