Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6620, here are decompositions:

13 + 6607 = 6620
43 + 6577 = 6620
67 + 6553 = 6620
73 + 6547 = 6620
139 + 6481 = 6620
151 + 6469 = 6620
193 + 6427 = 6620
199 + 6421 = 6620

Showing the first eight; more decompositions exist.
