Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551604, here are decompositions:

7 + 551597 = 551604
17 + 551587 = 551604
23 + 551581 = 551604
47 + 551557 = 551604
61 + 551543 = 551604
101 + 551503 = 551604
181 + 551423 = 551604
197 + 551407 = 551604

Showing the first eight; more decompositions exist.
