Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551778, here are decompositions:

5 + 551773 = 551778
11 + 551767 = 551778
47 + 551731 = 551778
61 + 551717 = 551778
89 + 551689 = 551778
107 + 551671 = 551778
127 + 551651 = 551778
181 + 551597 = 551778

Showing the first eight; more decompositions exist.
