Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549636, here are decompositions:

13 + 549623 = 549636
29 + 549607 = 549636
47 + 549589 = 549636
67 + 549569 = 549636
83 + 549553 = 549636
89 + 549547 = 549636
103 + 549533 = 549636
127 + 549509 = 549636

Showing the first eight; more decompositions exist.
