Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67680, here are decompositions:
- 29 + 67651 = 67680
- 61 + 67619 = 67680
- 73 + 67607 = 67680
- 79 + 67601 = 67680
- 101 + 67579 = 67680
- 103 + 67577 = 67680
- 113 + 67567 = 67680
- 149 + 67531 = 67680
Showing the first eight; more decompositions exist.
