Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545622, here are decompositions:

5 + 545617 = 545622
13 + 545609 = 545622
23 + 545599 = 545622
43 + 545579 = 545622
71 + 545551 = 545622
73 + 545549 = 545622
79 + 545543 = 545622
89 + 545533 = 545622

Showing the first eight; more decompositions exist.
