Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67660, here are decompositions:
- 29 + 67631 = 67660
- 41 + 67619 = 67660
- 53 + 67607 = 67660
- 59 + 67601 = 67660
- 71 + 67589 = 67660
- 83 + 67577 = 67660
- 101 + 67559 = 67660
- 113 + 67547 = 67660
Showing the first eight; more decompositions exist.
