Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79668, here are decompositions:
- 11 + 79657 = 79668
- 37 + 79631 = 79668
- 41 + 79627 = 79668
- 47 + 79621 = 79668
- 59 + 79609 = 79668
- 67 + 79601 = 79668
- 79 + 79589 = 79668
- 89 + 79579 = 79668
Showing the first eight; more decompositions exist.
