Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66616, here are decompositions:
- 23 + 66593 = 66616
- 29 + 66587 = 66616
- 47 + 66569 = 66616
- 83 + 66533 = 66616
- 107 + 66509 = 66616
- 149 + 66467 = 66616
- 167 + 66449 = 66616
- 233 + 66383 = 66616
Showing the first eight; more decompositions exist.
