Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545628, here are decompositions:

7 + 545621 = 545628
11 + 545617 = 545628
19 + 545609 = 545628
29 + 545599 = 545628
79 + 545549 = 545628
101 + 545527 = 545628
107 + 545521 = 545628
131 + 545497 = 545628

Showing the first eight; more decompositions exist.
