Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551550, here are decompositions:

7 + 551543 = 551550
11 + 551539 = 551550
31 + 551519 = 551550
47 + 551503 = 551550
61 + 551489 = 551550
67 + 551483 = 551550
89 + 551461 = 551550
107 + 551443 = 551550

Showing the first eight; more decompositions exist.
