Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67720, here are decompositions:
- 11 + 67709 = 67720
- 41 + 67679 = 67720
- 89 + 67631 = 67720
- 101 + 67619 = 67720
- 113 + 67607 = 67720
- 131 + 67589 = 67720
- 173 + 67547 = 67720
- 197 + 67523 = 67720
Showing the first eight; more decompositions exist.
