Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67648, here are decompositions:
- 17 + 67631 = 67648
- 29 + 67619 = 67648
- 41 + 67607 = 67648
- 47 + 67601 = 67648
- 59 + 67589 = 67648
- 71 + 67577 = 67648
- 89 + 67559 = 67648
- 101 + 67547 = 67648
Showing the first eight; more decompositions exist.
