Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551586, here are decompositions:

5 + 551581 = 551586
17 + 551569 = 551586
29 + 551557 = 551586
37 + 551549 = 551586
43 + 551543 = 551586
47 + 551539 = 551586
67 + 551519 = 551586
83 + 551503 = 551586

Showing the first eight; more decompositions exist.
