Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67818, here are decompositions:
- 11 + 67807 = 67818
- 17 + 67801 = 67818
- 29 + 67789 = 67818
- 41 + 67777 = 67818
- 59 + 67759 = 67818
- 61 + 67757 = 67818
- 67 + 67751 = 67818
- 109 + 67709 = 67818
Showing the first eight; more decompositions exist.
