Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6650, here are decompositions:

13 + 6637 = 6650
31 + 6619 = 6650
43 + 6607 = 6650
73 + 6577 = 6650
79 + 6571 = 6650
97 + 6553 = 6650
103 + 6547 = 6650
181 + 6469 = 6650

Showing the first eight; more decompositions exist.
