Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545556, here are decompositions:

5 + 545551 = 545556
7 + 545549 = 545556
13 + 545543 = 545556
23 + 545533 = 545556
29 + 545527 = 545556
59 + 545497 = 545556
73 + 545483 = 545556
79 + 545477 = 545556

Showing the first eight; more decompositions exist.
