Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89666, here are decompositions:
- 7 + 89659 = 89666
- 13 + 89653 = 89666
- 67 + 89599 = 89666
- 103 + 89563 = 89666
- 139 + 89527 = 89666
- 223 + 89443 = 89666
- 337 + 89329 = 89666
- 349 + 89317 = 89666
Showing the first eight; more decompositions exist.
