Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551556, here are decompositions:

7 + 551549 = 551556
13 + 551543 = 551556
17 + 551539 = 551556
37 + 551519 = 551556
53 + 551503 = 551556
67 + 551489 = 551556
73 + 551483 = 551556
113 + 551443 = 551556

Showing the first eight; more decompositions exist.
