Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67890, here are decompositions:
- 7 + 67883 = 67890
- 23 + 67867 = 67890
- 37 + 67853 = 67890
- 47 + 67843 = 67890
- 61 + 67829 = 67890
- 71 + 67819 = 67890
- 83 + 67807 = 67890
- 89 + 67801 = 67890
Showing the first eight; more decompositions exist.
