Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551562, here are decompositions:

5 + 551557 = 551562
13 + 551549 = 551562
19 + 551543 = 551562
23 + 551539 = 551562
43 + 551519 = 551562
59 + 551503 = 551562
73 + 551489 = 551562
79 + 551483 = 551562

Showing the first eight; more decompositions exist.
