Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6662, here are decompositions:
- 3 + 6659 = 6662
- 43 + 6619 = 6662
- 109 + 6553 = 6662
- 181 + 6481 = 6662
- 193 + 6469 = 6662
- 211 + 6451 = 6662
- 241 + 6421 = 6662
- 283 + 6379 = 6662
Showing the first eight; more decompositions exist.
