Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545872, here are decompositions:

29 + 545843 = 545872
83 + 545789 = 545872
113 + 545759 = 545872
149 + 545723 = 545872
251 + 545621 = 545872
263 + 545609 = 545872
293 + 545579 = 545872
389 + 545483 = 545872

Showing the first eight; more decompositions exist.
