Goldbach decomposition

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.
